@Bibio couldn't you also just use process HDR content by usin gpixel shader math, setting peak nits, and making sure "send HDR metadata to display is checked?

 That only works if your display doesn't activate its own tone mapping. This won't work for everyone. Mostly, the gamma can be changed and maybe some of the values will be further compressed. I am betting this only works with a few displays. They are pretty dumb when it comes to tone mapping, even when madVR changes the metadata to say that it has been compressed already. The display may not interpret this metadata correctly.

There is no nits value in the profile logic. Although, I don't quite understand what you are trying to do.
