I don't think it's currently exposed anywhere.

Hello,
is the information which color mode is currently in used for a display (RGB, YCbCr444, or YCbCr420) exposed to user space somewhere?
If no: Where would be the best place to put code to expose it to sysfs?
Hi,
a very good question. Wayland compositors implementing color management will be interested to know this, and even better, to explicitly control this.
See e.g. Color Calibration Auditing System notes in https://gitlab.freedesktop.org/wayland/weston/-/issues/467 .
Thanks, pq
@Alex Deucher thanks for the info.
