I believe Quato iColor Display allows you to do this without any license.

Your dispcalgui results, however, suggest that you have not calibrated the
display to D65 first though. The results are not directly comparable unless
they are all relative to the same white point.

The TFTcentral results show a different white point due to an oddity in the
ICC v2 specification, and so its different white point shouldn't be a
problem. THe primaries are also certainly translated from D65, as will the
NEC profile.
