It looks like it's going to require some form of iteration? There are some

to apply some correction, print the result and compare. If that's the case,
that will only be practical on proofing device which is probably what X-Rite
has been targeting. But that's not going to be practical for the press...
That will be because they haven't got any way of measuring the UV content
of the illuminant. A similar approach can be taken using Argyll's FWA compensation
by trying each of the UV modified D50 illuminant spectrums provided to see
which one gives the best correction.
