Wayland Color Management Protocol Might Finally Be Close To Merging

Can someone explain what this really does ? The article is very lacking.
- Color management ensures accurate and identical color reproduction across display devices. It's extremely important for artists and designers, and its absence in Wayland is a deal breaker for them.
  
  I would like to remind everyone that while this extension does not include display response measuring and calibration, they will come later.
  No calibration yet.
  
  Oh yeah I've seen issues in KDE Wayland for it lately, namely on brightness. It's gone since.
- 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.
Does this mean I could finally enjoy HDR content on my OLED HDR monitor?
- You can right now. If you are using KDE, it should work with mpv, though you might need to launch it from terminal with a few flags to tell mpv to use HDR.
  If you’re not using KDE, you can launch gamescope with the hdr flag in the tty and have it launch mpv.
  Though I’m not sure any browsers have working HDR. I think Chromium may have some stuff in progress. Gnome Web may get it since WebKit supports HDR and HDR is being worked on for GTK.
  
  gnome iirc also has merged the wip protocol so it should work on gnome too
  
  Do I have to enable HDR in Plasma settings? Because when I do, and then log out, plasma crashes and I have to log into a different DE and disable HDR in the terminal.
It's kind of embarrassing they still don't have this tbh.
- They as in Wayland? Xorg doesn't have HDR either and never will.
  
  As in Wayland yes. X does have color correction stuff, which is the most important part.
the Wayland color management protocol might finally be close to merging after four years in discussion.
But also
Going all the way back to January 2020
So really it's been almost 5 years.
Let's hope we can finally get it and move on to any other remaining protocols.
- HDR is new ground on Linux, so it’s understandable it’s taking a while. It requires involvement from all over the graphics stack: graphics drivers, mesa, Wayland protocol, protocol needs to be implemented in compositor, apps need to implement the protocol.
