Tom Lianza and Graeme Gill covered the issue pretty well--an appearance
model is used at the time that a rendering is created, so the issue
is whether print-time rendering is going to be useful and how it's going
to work from a systems point of view (i.e. where it's done, how it's controlled,
how to get an accurate and controlled proof, etc.)
The motivation behind my previous question was to figure out whether your
request for CIECAM02 was based on a need that CIECAM02 addresses, or whether
it was to solve a different problem, such as image-dependent gamut mapping, which is
independent of whether CIECAM02 or another appearance model is used to
create the rendering.
Finally, the paper by Moroney and Huang that was previously mentioned was
evaluating how well CIECAM02 behaves as an interpolation and gamut mapping space,
which is an important question, but also not so relevant to the issues at
hand, i.e. whether CIECAM02 is "used" in ICC/ColorSync, and what that would mean.
