Using BabeColor CT&A's ISO-3664, I remember measuring something like
98 for
the CRI and a Grade B in the CIE012 test panel. Something I had
never seen
myself in all the luminaires I measured with this software and my
EyeOnePro
over the last four years.
ISO 3664 says (under 5.1 Spectral measurements):
The bandpass of the measuring instrument
(spectroradiometer) shall be 5 nm or narrower.
this rules out the EyeOne Pro (even if it very valuable in related
issues such as process control)

PS: There is a bunch of reasons why this is needed.
Also note that not all softproofing is done with a
viewing booth/hardcopy comparison.
But all softproofing at the press is to be done with a view booth/
hardcopy
comparison, Mike.
The hardcopy happens to be that of the printing press. But granted,
there
are empirical tweaks used by the monitor profilers to help improve
the match
between the view booth/harcopy that probably go beyond calibrating
to plain
D50. But, to the best of my knowledge, they don't necessarily use
white
point deviations. I still have to digest Chris Edge article
presented in
Portland's CIC.
My .02 canadian cents that are now worth less than your .02 us
cents :(
