And there's no kernel parameter for it, see: https://bugs.freedesktop.org/show_bug.cgi?id=96489 So if the Wayland compositor does not provide an option to adjust it, you're pretty much stuck. I guess this is the list of all those "connector properties": https://01.org/linuxgraphics/gfx-docs/drm/drm-kms-properties.html ? May I ask why this has been set to "wishlist"? This is not just a fancy feature request. It's a real issue if you're affected by the automatic setting not working properly. The Weston devs seem to take this more seriously, see: https://bugs.freedesktop.org/show_bug.cgi?id=99406 > May I ask why this has been set to "wishlist"?
We have bugs and wishes. Anything which is not an existing feature is a
wishlist. Currently KWin does not yet support this, thus it's wishlist.
I strongly agree. Plasma on Wayland is shaping up nicely, but the picture is washed out on my hdmi monitors due to this issue.

Bug about washed out colors https://bugs.kde.org/show_bug.cgi?id=398898 I suggest that this also needs a visible toggle in Plasma settings ("Hardware"\"Display and Monitor"\"Displays"). Some people may even not realise that their displays work in the incorrect mode, at least a visible option in the GUI could interest them.
The most detailed discussion about the whole situation with colour ranges that I am aware off:
