Yes, it does :) I won't waste too many cycles on this. But, it's a shame to waste meta data.

Adobe spends a lot of effort on duplicating this provide in different places.

I do notice that when I use graphics magick on this particular TIFF file, I don't get the warning

about incompatible tags. Do you know why there is this discrepancy?

It supports TIFFTAG_PHOTOSHOP and TIFFTAG_RICHTIFFIPTC but only uses TIFFTAG_RICHTIFFIPTC if TIFFTAG_PHOTOSHOP is not defined, so it seems that it never really uses TIFFTAG_RICHTIFFIPTC at all.
