If I did get the whole thing correctly, this might be equivalent to disable
CMS.

Not sure at all if my workflow is "better". I did build a specific profile
for my LS4000 using freeware (LittleCMS) and the Kodak IT8 target. I do all
my scans at 14 bit depth with Nikon CMS disabled. When opening the file in
Photoshop I just apply that custom scanner profile and convert to my
standard working space (Adobe1998 RGB).
This produces kind of satisfactory color balance to me, quite similar to
what I needed VueScan to achieve before setting up this protocol. However,
different situations, film and scanning resolutions would probably need
different profiling even with the very same scanner unit.
