It's tagging with each profile which is what's so odd.
I do have a conference call with LaserSoft tomorrow but I think I may have been using the settings incorrectly (so Mark, here is a chance to comment).
I updated the settings in CMS preferences and now I do see a major difference in the scans in terms of deltaE and saturation with Standard vs. Advanced profile. Below are the settings I used, different from the first test where the dE's were nearly the same. This setting seems to be 'correct' in that I believe only the conversions are to the scanner profiles but I find it odd that they are not embedded as shown. When I examine the differences in the two scans, the deltaE is quite large!

Also see a visual of the differences with ColorThink Pro below. Again, I need the ear of LaserSoft engineers and/or Mark to verify that this is the best way to scan the same print.
