Allow Limited and Full RGB Range Selection in Wayland via "Broadcast RGB" DRM Property
#1461
With KDE Plasma 6.8 dropping support for X11, I'm no longer able to select limited color ranges for HDR content, which leads to greyish output for many HDR displays that expect limited color range inputs or have weird quirks when provided full range, eg my LG C6H lowers its peak brightness with the default full rgb range.
How easy would it be to implement this property for Wayland?
For context, I discovered the source of the problem via this KDE Plasma bug report:

Uh oh!
