Graeme, I've noticed, that V0.53 seems to choose a too light "black" for perceptual intent (noticeably lighter than the darkest reproducible neutral L*, at the relcol. [a*,b*]==[0,0] locus), which also results eventuelly in a "washed out" or low-contrast appearance. This seems not to happen in previous versions - their perceptual intent renders black darker. I haven't yet attempted to analyze the root cause. Might it be related to the skewed perceptual gray axis issue, I had discussed with you? Did you probably already include some changes regarding this issue in 0.53, which might lead to the behaviour we see now?
