Hi,
cLUT based profile typically have 3 tables, one for each intent.
Photoshop
is letting you choose which table to use. If you don't generate a perceptual
and saturation table, then the one colorimetric table will be shared by all
three intent tags, so you will get colorimetric intent no matter which
intent you select.
[ie. the Photoshop selection is a mechanism, not a final result.]
