These values will vary with each setting selected in ProfilerPRO. So unless
someone writes a handy utility to sample 729 patches and list their Lab
values, the only way to do this is to sample them by hand, and note the L, a,
and b values as closely as Photoshop will list them, in order in a text file.
That would not be a trivial task, and would need to be repeated for each
different setting used in building different profiles. It might be easier to
simply select a few gamut edge colors, note their Lab values in the text
file, and then check them against the same patches on the original CMYK
target, using the same settings.
