Note: I would not recommend to use an ICC profile from another person. It can help, but It also can downgrade your image quality. The Samsung already has good settings out of the box. Just set your color temperature to your FAVORITE. If you want a "darker" gama value, then you also can just change within the OSD, which is more recomennded compared to changes within the graphics cards settings
Very important to the topic "the optimal OSD settings".

Newest Update (HDR) Ps4 Pro and 4K Blu-Ray Player and a direct comparison
Measured contrast, brightness and black point
IMPORTANT: These both extra CONTRAST measurings are measured @ perfect Local Dimming conditions. They will never occur in a game btw. View the Review for more informations please.

It helps a bit, but I couldn't find a solution to add this in chrome. chrome://flags/#enable-direct-write does not help and within the chrome://flags/ direct write is missing.

Adding the Font Rendering Enhancer in the chrome addon also can help
II. CS GO (Purple Trails) and "Input-Lag"
Don't become a shock. In CS GO I first time could see purple trails, not artifacts. They are VERY slightly visible and this makes it even harder to capture on camera. Within a video, no chance. They occur mostly in motion blur. CS GO is the first game which makes problems within this monitor while Freesync also does not work appropriately. Reducing tearing works but the game still has stutter. I also read about problems within Freesync and source engine games in general.
1. A tiny bit purple trails
2. Models in darker areas have more smearing (sometimes the smearing is brighter than a model *overshot*)
3. CS GO has pretty many stutters, but within 31.5 Inch and especially within a VA panel you can see this much better than on a 27 Inch TN Model, so This isn't a good choice for CS GO
4. After playing 30 minutes CS GO on my TN with a friend and switching to the CHG70, I could feel a small difference in input lag. It was pretty strange that this wasn't visible in a 1:1 comparison, and it's pretty hard to see the difference. The only way is expensive measuring hardware or much experience within CS GO and 144 Hz for years. So in the end, the input lag is still good within the CHG70, but there is a slight difference that I could feel. The Samsung and ALL VA panels are not for competitive FPS games in my opinion. Games like Battlefield 1 etc should be okay. But even here (Competitive FPS like CS GO, Overwatch) I recommend a 24 or 27 inch monitor (IPS or TN for FPS enthusiasts while I also can see a difference between IPS and TN in these games). So consider, VA is the slowest panel type within TN, IPS, and VA.

Some people won't believe, here is the ultimate evidence (I said Freesync does not work above 80 hz / fps, ofc I meant below 80 hz / fps)

HDR Update *Mass Effect*
Finally, I could enable HDR in Mass Effect. But the results are pretty bad. Almost the same as I just would activate HDR within windows and play just some game. I strongly assume that this is an issue within the software, but I cannot confirm for sure. It also can be that games, especially mass effect (but this would be strange) just look bad with HDR, especially with this "low" brightness.
Update 2: Mass Effect and HDR
I've read some articles that Mass Effect Andromeda in HDR looks (sometimes) washed out. Especially the menu will lose color intensity. So some places look better and some worse compared to non-hdr game content. Based on this video https://www.youtube.com/watch?v=cgBzpYT ... u.be&t=103
and this Review
https://www.gamecrate.com/samsung-chg70 ... view/16348
they say depending on the Image content sometimes it looks worse, sometimes it looks better. You have to consider, HDR currently with current game content looks so bad to me on the CHG 70 that I thought there is 0% HDR support. Especially in games, it's probably pretty hard to benefit from HDR while within movies mostly profit from HDR. And even in movies, it's mostly not like another world and sometimes is the difference pretty slightly. So I think it also depends strongly on how good a game is programmed or how good a movie is recorded. While the movie "Life of Pi" looks awesome on an HDR 4k TV and "The Revenant" pretty decent into my eyes.
I talked about bad black levels within HDR, but I think this is just because it looks like you have a contrast around 400:1 or something. Even standard mode on contrast set to 0 looks better.

Regarding the Backlight-Scanning / Strobing Feature
It is not possible to enable strobing on 60 Hz
PS4 | 4k Blu Ray Player:
- A Blu Ray Player I will organize tomorrow with an HDR movie
- PS4 still searching for someone who has a ps4. All my friends are pc enthusiasts... I really hope I can organize one to test HDR compatibility within the CHG70 and a PS4 Pro
Will follow as soon as possible (HDR Console / 4K Blu Ray Player)
Currently my thoughts about the CHG70. Don't buy if you're just like me and take a closer look at the smallest issues ;D In general, a very good monitor with some Issues within Freesync, vertical scanlines, and text inversion. The HDR feature is still a bit disappointing but as far as we know, games are not that optimized within HDR. I think Samsung would do better if they wouldn't promote HDR so aggressively within the CHG90 while it is in our nature to think that if something is not working properly is a bad product.
At HDR you can see the monitor does not flicker, this is because the brightness settings within the OSD are set to 100. Everything "under" around 200 cd/m2 starts to flicker
Samsung CHG70 HDR Update Conclusion Overview
HDR has currently Problems on PC which will be fixed for sure
Even with these fixes I would not recommend the CHG70 for HDR content
and especially not for HDR Movies on a 4k Blu-Ray Player
1. Too dark (not enough brightness, check the link in the video description for current
Samsung brightness issues within displays.
2. Not enough dimming zones. Of course, direct LEDs or dimming zones are not needed
necessarily, but they can improve the overall image quality drastically, especially within HDR
HDR on the PS4 looks amazing
1. Sometimes a bit worse sometimes better on the CHG70
2. Within the game "Horizon" it looks awesome and I already can imagine how good
this will look on an appropriate display
3. Nevertheless, WQHD on PS4 is not optimum. If you play on 4k the PS4 downscales to 2k - you still will have a sharp image but with the disadvantage of lower framerates while the game still is rendered in 4k. On Full HD the Monitor has to downscale and a native Full HD monitor will be sharper than a WQHD Monitor. So in the end, with WQHD on a console you can't profit within 4k and loses sharpness within Full HD, you should keep this in mind.
Very informative Video from RTings:
Samsung brightness issues within TVs, maybe this also occurs in my CHG70 while I've measured "only" 470 cd/m2.
HDR in general
Depending on how a game/movie is recorded, developed and programmed:
It can really improve the image quality clearly visible(!)
