I’m on a Sony OLED with a 3090. I game some, and color grade photos/videos in HDR.

…And I can’t get HDR to look right in KDE, even with the display running off my AMD IGP. It has basically zero options for me to tweak.

So I use Windows for that.

Honestly, it’s hard enough on Windows. It’s a coin flip as to whether apps works or not, and the TV needs adjustments for some, lest they crush black or blow out highlights/colors. Many games, specifically, need configurable mods to look right.

One of my saddest video workflows is transcoding on Linux, and downloading the result to my iPhone to see if it looks right.
