Is there a tag I can set to distinguish between 3 band (24 bit) monochrome, where all three bands have equivalent pixels, and 3 band color (RGB)?
True RGB would use PHOTOMETRIC_RGB. Are you saying you have a file with PHOTOMETRIC_RGB but it really contains 3 monochrome channels? Or is the file PHOTOMETRIC_MINISWHITE/PHOTOMETRIC_MINISBLACK with SAMPLESPERPIXEL = 3?
For PHOTOMETRIC_RGB, SAMPLESPERPIXEL=3: I would guess that R, G, B samples would all be the same value (R=G=B).
