I think HDR in Linux is still a long way off. Wayland seems to have
started working on it these days. Monitors and TVs claimed to be HDR
are mostly Fake-HDR. However, you can't have HDR without Color
Management.

10-bit works. You can get DCI-P3 with proper colour profile. Just use x11. You probably read about wayland where these are work in progress. Btw, linux itself may support 10bit colour, but same can not be said for other software that runs on linux.

Just put DefaultDepth 30 in /etc/X11/xorg.conf.d/ (default value would be 24). If you also run kde, consider running echo "export KWIN_OPENGL_INTERFACE=egl" >~/.config/plasma-workspace/env/use_egl.sh also, as kde may crash otherwise. With above changes, 10-bit colour works for me in kde

I wonder how THOSE color profiles look ....Do you have one? Can you run some testing/introspection programs on it?

Features

CompICC uses Oyranos to configure the ICC profiles for each monitor. The order of monitor configuration inside Oyranos is, first look in the Oyranos DB for a explicit configured ICC profile, if no then scan the installed ICC profiles for one matching the to be setup device, if not generate on the fly from the monitors EDID data block, if not try from the Xorg log and as a last means take sRGB, if not fail miserably ;-)

  • instant desktop colour correction on GPU with compiz
  • multi monitor support
  • ICC Profile in X support
  • X Color Management 0.3 DRAFT1 support
  • EDID -> ICC profile on the fly
  • 16-bit per channel compositing
  • hotplug capable
  • wide gamut monitor calibration
  • support 30-bit monitors

I wonder if you ever get better result by using those system-wide methods .....

====
Krita supports with the OpenGL backend even native 10-bit per colour component. Menus in Sketch are black. Krita shows minimal artefacts through twice colour converting from image to sRGB by Krita and from sRGB to the monitor colour space by CompIcc. But this effect is much lesser visible than the improvements through its 30-bit support.

sooooo ... it was kinda  working (probably with nvidia quadro?) back in 2014 ...

I never heard about THIS color management system before ....
