it may be possible to take the readings and create a 3D LUT with it.

I think that the DisplayCAL can't do this

ArgyllCMS can (at least in principle) generate a 3DLUT from any ICC profile using the collink -3m command. See the documentation, especially the section about madVR at the end of the section.

This information would be useful in the madVR's help. It's terrible to imagine how many people see not flawless colors

Most people do not have a colorimeter or even know what a gamut is to begin with, so while I do agree with you in principle, I think you are mistaken about people's priorities

Windows cannot "load" ICC files, per se - or at the very least it would be quite misleading to say so. It can load the vcgt (GPU gamma ramps) that's within an ICC file (and even then, only if you tick the right checkbox), but that's only a small part of the data contained within the profile, and it can only be used for basic gamma and white point adjustment - not for gamut mapping. It's the responsibility of each individual application (e.g. Photoshop) to load the full profile and come up with a proper color space transformation.

Сonfusion with the purpose of the settings in the madVR, especially "disable calibration controls for this display" and "this display is aleready calibrated" does not give an idea of the actual situation

Hmm, pehaps we are too close to it but the "disable GPU gamma ramps" should clue you in if you understand how calibration works in Windows. Those options are designed for those who are familiar with Windows calibration because they are the only ones who ask for the feature at all.

It can be very difficult to come up with short descriptions that are clear to everyone. With the knowledge that madVR does not reference ICC profiles everything else should be clear. Please check out the link in my signature and let me know if anything does not make sense to you.

Does it not? DisplayCal supports the common meters, X-rite or Spyder. Which meter are you using?

That doesn't support a lot of possible ICC profiles, I couldn't get it to work using ICC profiles created by X-rite's i1Profiler.

Just based on madVR options, there can be a persistent feeling that it will use the ICC profile, simply as EVR do. I think that the warning that this is not so, will be useful.

I use NEC MDSVSENSOR

Personally I think it would be nice if madVR could load say LCMS as an external dll or something and generate its 3DLUTs on the fly from the monitor's ICC profile for each target color space. The resulting 3DLUTs (which could be cached somewhere) would presumably be of somewhat lower quality than using ArgyllCMS' collink, but I think it would significantly increase the number of people receiving color correction (even if they did still have to download LCMS separately due to licensing or whatever).

Wow, EVR uses an ICC profile in Windows 10 now? That is new and great news, it is almost weird having Windows finally support color management. I remember recently thumbnails started being corrected but Windows assumed you had an sRGB display so it would convert anything tagged something besides sRGB to your profile as if your profile was sRGB (counter productive on my DCI-P3 displays). I need to do more experimentation with 1607.

No. If I use the "Use Display ICC Color Gamut Correction" in the PotPlayer, then the colors match in the PotPlayer, but only for EVR, does not work for madVR

It would be fantastic!

Ah, it is just PotPlayer hacks then.
