in Photoshop.
I think you mean the ColorSync filters that rely on the default CMM.
Any Mac with ColorSync installed will by definition also have the
default CMM available. The definition of device independence is a
transform in default mode.
A test that revolves around ColorSync is one thing, a test that
revolves around an application is something else again. Photoshop 5
uses other code paths and an internal color management method which
is proprietary to Adobe. The technical status for Photoshop 6 is not
clear.
Excluded from a test of ICC compatibility is also ICM1 by Kodak where
the CMM only supported 8 points while ColorSync supported 32.
The CMM / API / application / driver / RIP matrix is very, very
complex. However, the idea of such a test is intriguing.
