I've been wondering if absolutely white areas of the print (RGB=<255,255,255>) are not tinted at all, leaving the just base material color? If so, it may help to replace absolute white with off-white (e.g. RGB=<254,254,254>).
This is pure speculation on my part, however.
(Edit: comparison of the printed 3D relief cat with the photo suggests that this is probably
not the case.)
