Check this talk out, it is an interesting talk by a wayland dev.
In my opinion most important points from this talk that wayland proponents and fans who say we should use it today right now need to understand is :
- Colour profiling and calibration is not ready right now.
- All or most apps are now in legacy mode which is sRGB only
Also listen to the very first sentence they say - " the end goal is getting HDR in wayland but getting HDR means getting colour management right"
So when I earlier said that we were lucky that colour management and HDR have common things, otherwise we would be left behind without a thought, is this point. Their main target is HDR for gaming and multimedia, it is where the funding comes from and not print design or digital artists etc.
