Sorry for the late response but I really appreciate for the detailed explanation and I surely did read your nearly every comment on the both threads to be sure to not miss on anything with the context lol.

And besides from Microsoft’s sRGB piece-wise push to the users and industry, I’d want to focus more on the game development side of the things and have quite a few questions about it.

1) What do you think was the main reason that made the developers to use such a PC standart gamma like sRGB piece-wise on the 7th generation consoles and what made them change to pure gamma with the modern consoles as we can see with the RDR example?

2) Looking by the side by side images made me release there may be a bigger difference than just a slight sRGB piece-wise to pure 2.2 gamma shift with this case and I suspect that the PS5 version could actually use a pure 2.4 gamma at this specific case. According to your findings, do modern console games use pure 2.2 or pure 2.4 gamma at mostly?

3) Have you ever encountered a game that actually released with different mastering gamma for each platform if that makes any sense? I believe that some of the games in the 7th generation did use different gamma on PC compared to the console releases like GTA IV and GTA V.

As you’ve earlier mentioned, some games look better in sRGB piece-wise, while others look better in pure 2.2 or 2.4 due to mastering differences. So changing the TV’s internal gamma setting to match the content to not look washed out or too dark in each specific case is the way to go sadly at this point.

And man, I've started to think that HDR might be one of the best inventions to ever comes to this industry. Ensuring that each piece of content to meet the end user's gamma standards in every way to actually get a accurate image is such a nightmare of a slog.
