Hmm. Since the i1pro2 has a wavelength reference LED in it for calibration,
that suggests that maybe the LED itself has shifted. It would
be fascinating to know if that was the case. Perhaps one way of
getting a hint would be to check using ArgyllCMS spotread
with and without the ARGYLL_DISABLE_I1PRO2_DRIVER environment variable
set. (When treated in backward compatible fashion, the wavelength calibration
is not performed.)
[I'm assuming that you are seeing the same measurement values using X-Rite's
software and Argyll ? ]
