All CMYK TIFF files should been PHOTOMETRIC_SEPARATED & SAMPLESPERPIXEL == 4. Some will have INKSET(332) == INKSET_CMYK. TIFF/IT-P1 files will have NUMBEROFINKS(334) == 4 and INKNAMES set to a string of the individual separation names.

You will encounter both planarconfig types PLANARCONFIG_CONTIG and PLANARCONFIG_SEPARATE.
