I actually upgraded to Windows 11 specifically because I was told they fixed HDR. I do have an RX7600 so it’s technically “last gen” but I’m running DP (I have no idea which version but it has to be at least 1.4 because it runs 1080p at 180Hz). Washed out SDR content isn’t that bad, I actually didn’t even notice until I dragged a window playing SDR content to my second monitor that doesn’t have HDR and the blacks looked, well, blacker. I don’t doubt that it’s worse on Linux, I wasn’t trying to defend it. Just wanted to point out that it seems like no OS that isn’t designed to run only on TVs gives a crap about the HDR experience.
Yep. 4 is a terrible sample size, I didn’t even look at the results since the point I was trying to make was about selection bias, which you seem to understand so I don’t know why you even thought posting the previous comment was a good idea.
I’ll apologize for calling your comment stupid, though. That was unnecessarily hostile of me and uncalled for.
