Hi, it's a pity you've given up before providing any concrete information to go on. It's not clear to me for instance whether the problem is in calibration or profiling, what parameters you were using for both, whether the profile is the simple one from dispcal or the more sophisticate result from colprof. If it's the calibration, then the dispcal parameters + output of dispcal -v2 would be a good place to start in understanding what the problem is, together with some spot readings of the resultign grey patch values from dispwin -m, say starting with an absolute reading of the white, and then using spotread -dw from white to black.
