Could everyone still having the problem check if an ICC profile is set for his display by running:
xprop -root | grep ICC_PROFILE
If none is set the grep should be empty (besides a possible _ICC_PROFILE_IN_X_VERSION entry).
If one is set unset it with
xprop -root -remove _ICC_PROFILE
the check the image display. If it is okay then, it is most likely an issue with the profile.
(NOTE: These steps may not work correctly on a multi-monitor setup!)
