This is possibly because the atom has been
renamed from EDID_DATA to EDID. dispwin will catch
up to this in a future release.

Nothing here indicates a problem, dispwin thinks it set
the video luts.
You could double check by creating a strange looking calibration:
synthcal -s 0.7,1.0,0.9 -p 1.7,0.8,0.7 strange
and then see if it gets loaded:

If the above confirms that the video Lut load is not being honored,
perhaps the best thing to do is to file a bug with xorg.
