ICC used to have a "print reference medium"
http://www.color.org
I don't know if they still have it
it was the only attempt at appearance matching as opposed to color
matching I saw
ICC ought to have appearance tags in their input/output/etc. profiles
they would also need the CMM to flag incompatible appearances
incompatibility is like trying to render a print appearance to a
transparency/translucency/projection appearance
(I ran into this at Kodak)
you can't really unbuild a compressed appearance gamut like print or a
small RGB space to a bigger gamut, this is like creating information,
except maybe in consumer applications where a larger tolerance is
accepted, like cell phones
I realize appearance is also image dependent and you can't do much of
that with ICC or pro images, leaving some work for editing, Kodak had
scene balance algorithms that worked well for consumer images (reducing
the number of edits to zero in most cases)
