It works in KDE + Wayland… mostly… for applications that support it… and there was this update that ruined my color profile for a while but they fixed that now!

It’ll be finished on Wayland before the end of this year

first game I played in HDR was mass effect legendary. I don’t care that the game itself is close to 15 years old, the 4k remaster + HDR blew my mind and set a new standard for how good games could look.

It does work for most games. MPV player supports it as well. It’s still rough around the edges, but it’s definitely there.
