I don't get that impression. Most of the difficulty seems to be
in making practical the spectral capture and spectral reproduction
equipment. The aim is very straight forward, reproduce the exact
reflectance characteristic in a copy of an original. If successful,
this means that it will look very similar to the original to any
viewer, under any viewing condition. There is no editing or
color management as such.
The only trickiness is in choosing the optimum compromise given
the limits of the capture and particularly reproduction equipment.
Given that you can't exactly reproduce the spectral reflectance
at a particular pixel, then which reproducible spectral profile
should you choose ? The sort of solutions talked about are to
use a tri-stimulus color control loop around the spectral
one, so that at each point you choose a spectral profile that
has an error that is weighted firstly to have minimal tri-stimulus
error, and secondarily to have minimal spectral error.
