isn't this the XYZ relative to an ideal print?

No. XYZ is a perfectly additive space based on physical intensities and
spectral curves based on work of the CIE.

I'm pretty sure it is.

You are confused.

There is also the difference between color matching and appearance
matching.

Which is irrelevant for the question of the profile connection space. It
is the matter of how an ICC color management module implements the
conversion between source and target space.

Appearance matching can be image dependent so you would have
to use some kind of scene balance algorithm, SBA , which doesn't quite
work for professional images and is best left to the image
editor/artist. SBA can prove good enough for most consumer images.

And your point is?
