I was able to create a profile with the web server, it works perfectly. 
But I was unable to create a profile without the VCGT tag (and thus have 
non-linear gamma). Should I use tone curve with gamma = 1.0 (relative or 
absolute)? In the mean time I applied the calibration from .cal file 
with applycal, but I would like to have a profile directly created 
without this step.

Another issue with my profile is that Argyll showed average dE of 0.41 
and max dE of 1.6 for my profile, but when I displayed L*a*b* of 30, 0, 
0, with the same display brightness, my meter (colormunki design) 
measured L*a*b of approx. 49, 0, -22 (I applied the gamma from VCGT 
after color conversion). Profile is a LUT based one and was created in 
complete dark and from 238 patches.

Another option is that Argyll's spotread does not work correctly with my 
colormunki meter (or the meter itself is broken). The color looks like a 
neutral gray color, without a tint compared to my x-rite color checker. 
I tried to measure a perfectly gray (i.e. "a" and "b" to be as close to 
the zero as possible), I got to a Lab values of 49.39, -0.16, 0.43 and 
the color on the display was strongly yellowish/brownish. Any ideas? 
Thank you.
Regards,


Martin
