The ICC format has long supported greyscale profiles. With
one of the later versions of the standards, the restriction
that Lut based profiles have a dimension > one was lifted,
allowing full single channel device -> PCS characterization.
The question is really what CMMs/CMSs fully support greyscale
profiles. I experimented with Photoshop and the Kodak CMM at
one stage, and unfortunately they had the opposite idea of
which device value represented white ... (Probably an ICC spec.
problem if the truth be known).
