No.
Wide gamut of display in Windows is not correct by ICC profile - this is a problem of the operating system. However, in XnView desirable option settings saturation, as has been done to adjust the gamma.
So understanding that the answer to my question in the current version of XnView does not exist? This is bad, because most monitors have now produced with wide gamut.
No. I have display with wide gamut. I use XnView as viewer of photos. And I want, that XnView decrease saturation for view all photos and not just group photos.
