I'm trying to get to grips with color calibration and profiling. As a first exercise, I'm trying to calibrate/profile my crappy 15'' laptop display using an i1pro (Rev B).
Now something puzzles me: When I do a calibration to D65, sRGB-Gamma, and create a profile for that, obviously only the grey ramp can be calibrated using the graphics card LUT.
However, to my understanding, when evaluating the profile quality using profiling software (basiccolor or icolor), for a matrix profile, shouldn't at least the primary colors have a very low deltaE? What I'm seeing is very high deltaE (5-6). White (255 255 255) has deltaE =0, and the whole grey axis looks more or less ok. So why are the primaries so far off?
As far as I understand, a matrix profile stores the primary colors (R,G,B) in XYZ-coords, and a correction table for different luminances for each primary. But the color (255,0,0) should map exactly to the color of the first column of the matrix, since that's just the XYZ of the primary color. So why is there any deviation at all?
Further, is there any software that displays the profile along with the values measured for the profile validation (best in a 2D view), so I could understand where the deviation would come from? A plot of the gamut + the 3 primaries + the measurements for the three primaries would be great...
Thanks!
