We have SLRs here that allow us to turn all white balance management,
sharpering etc off and do raw of course.

Are you saying the scanner isn't much better than the colorimeter or
that the scanner is much better than the camera?

We do have scanners, but they are all text-quality cheap stuff.  I
would expect I can get better range with our cameras.  Of course
consistent light but a no-window room and a specified set of lights
and angles should do that.
