Hi,

what kind of video standards would that be?

I'm wondering if it would have anything to do with Wayland color
management and HDR:

https://gitlab.freedesktop.org/pq/color-and-hdr
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/183
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14

Would there need to be any XDG standards to support color managed HDR
desktops, or is the window system support enough?

I have not much in my mind, but then I've been staring only at the
window system interactions, and haven't seen what else the desktop
ecosystem or applications might need.

Recommended display calibration and measurement procedures maybe?

Desktop viewing environment standards?

Viewing environment measurement?

They could be as straightforward as referring to a freely available
ITU-R or SMPTE papers or others, if there are suitable ones.

Thanks,
pq
