This is the protocol for HDR content. KDE already ships an experimental version of it.
not just hdr stuff, it’s all color profiling. my old monitor is dark af with wayland because it’s not loading its color profile and i can’t adjust gamma or apply color profiles in settings or with colord like you can in x. i really need this to be able to switch to wayland.
I know this is probably not a solution to your problem, but maybe:
This protocol isn’t relevant for your compositor to apply an ICC profile. If you’re using KDE Plasma, you can just select it in the settings. I think Sway allows that now too. If you’re on Gnome, you’ll need to wait.
I may need to look into this, because the colours between my drawing tablet and main monitor are quite different.
i’m using kde on endeavouros. when using wayland the color profiles section in settings does nothing. you can go pick a profile and click ok but it just doesn’t load it. colord is the daemon that handles color profiles entirely and that’s what this is about.
