Have you tried comparing the actual HCT-Velvia reference data to
AdobeRGB (or whatever) vs. what the scanner profile PREDICTS the

the Velvia target that push the gamut as far as the profile thinks.
Just curious.
I've done exactly that. The bright yellows are way outside Adobe RGB,
but so are pretty much all the dark saturated colors.
I've made scanner profiles that match the reference data to an
average delta-e of around 1.2 and a worst delta-e of around 3. The
HCT target contains colors that are outside the Adobe RGB gamut
by >15 delta-e...
