Marco, I think nobody did object this in the course of the discussion
(for many of the mailing list subscribers it likely self-evident).
But IMO the major focus of the discussion at this point in time was
rather to find an answer to the question:
How can it happen, that a (dumb) perceptual transformation between
two profiles (i.e. just apply the A2B0 and B2A0 tables) can still
result in a black point mismatch, making BPC necessary, although it
seems to be commonly accepted that the gamut mapping of perceptual
intent is expected to map source black to destination black?
Regards,
Gerhard
