Well, I've gone through the complete loop. First, dispcal, at 5000K. Then, targen with (only) 64 patches. Then dispread, taken into account the .cal file, which resulted in a .ti3 file. Finally, made an ICC profile from the ti3 file. So far, the result is less than stellar. Something did not work right. This is on a Eizo CG21 that is presently calibrated internally with a one channel 10bit LUT at a gamma of 2.2. Calibrated white point is D50. The VCGT in the Eizo profile shows linear curves. When I launch dispcal, I'm starting off linear curves in the video LUT. That, I suppose, should not be the cause of my problem. Where I suspect the problem lies is at the dispread stage. Somehow, when dispread launched, after calibrating the DTP94, applying the .cal file, the screen dramatically changes appearance. I usually have my desktop filled with a gray background image. This image turned sort of bluish-greenish when dispread launched. And I could see the white point going very yellowish. Going to experiment further...
