Do these sample names have any relevance, or are they arbitrary?

If the Lab a and b can be zeros, what about the XYZ data?  That data seems
redundant of the Lab values.

Yes, they seem like they would be.  That's why I'm exploring that approach.

I agree.  I happen to like the Epson driver, but I also like the ability to
tweak fine tune the ramp.  So, the Print with Preview, with an ICC or TF as
an alternative, seems like a good way to go.
