P.S. I've compared high resolution spectral mode vs. normal spectral mode on

popular display types (CCFL- and LED-backlit; standard and wide gamut). There

evident collorimetric difference between Hi-Res and Normal modes. Max deltaE
[CIE 1994]
was less than 0.3 P.P.S. I used an i1Pro (Rev. D).
On my CRT monitor I get DE's of:
White 0.669815 '94: 0.635949
Red 1.238462 '94: 0.482935
Green 0.923645 '94: 0.306630
Blue 1.372940 '94: 0.330161
Cyan 0.608738 '94: 0.375159
Magenta 1.117117 '94: 0.289138
Yellow 0.856135 '94: 0.544060
Whether that is of any significance, depends on your context. If it is of no
consequence
to you, then I guess purchasing an instrument with 1 nm resolution is not on
your
agenda :-) [Note that I currently have no means of verifying whether the above
differences represent an improvement in accuracy of not.]
