One thing to keep in mind is the difference between a connection space
and
an interpolation space. The ICC standard uses CIEXYZ or CIELAB as a
profile
connection space ("PCS") but LUT-based profiles have tone curves and
matrices so that
they can transform PCS coordinates into a different space before
interpolation via
a multi-dimensional LUT. The particular interpolation space used is up
to the
designer of the profile.
There's evidence that CIECAM02 is a better interpolation space than
CIELAB.
However, there are also other spaces that are better interpolation
spaces than CIELAB, but are much simpler. If all you're doing is
interpolation,
there's no reason to get bogged down with a complicated appearance
model.
