This profile was created using iColor Display in reference mode using the recommendations for the ProPhotoRGB color space (6500K, Gamma 2.2) 

Note that this profile has a device white point set to D50 rather
than the actual instrument read white point, and hence the absolute
colorimetric behavior is the same as relative colorimetric, and
will not match a profile (such as those from Argyll) that use
instrument readings for the absolute colorimetric intent.

Thanks for this hint! That also explains why the profiles created by the two different applications seemed to differ so much. The web tool used for comparision must have been set to absolut colorimetric intent. I did a comparision myself using relative colorimetric, and the two profiles were close to exact matches!
