I built a LUT based profile with the Spectorlino for my PowerBook LCD a
while back. Though the screen previews looked decent in PS6, comparing the
ICC profile to target data showed the profile to have an average delta e of
10! Obviously, not a good solution but interesting to note. PS. I am able to
load that LUT profile in the Monitor control panel with no problem.
