If you're talking about subtle differences in color on transparencies,
the scan introduces an extra level of interpretation that is imperfect. 
But if you're talking about acutance or distortion, I don't see why a
monitor would be unable to display this from one of these 10,000 dpi
scans.  We are just talking about magnifying a small portion of the
image so that very fine detail is visible.

Certainly even with 2700 dpi scans I can see that Royal Gold 400 has
larger dye clouds than Royal Gold 100.
