Your settings seem to be good, although I do have a small question about your monitor’s color set to Custom. That usually means that it is set to something - but it’s something other than 9300, 6500, etc. It would be nice to find out what that something is.
A bigger question is your setting the Optix to calibrate to D50. For most professional photographer’s purposes, that would make your display rather warm. Most people would start at somewhere around D65 (6500 K). So is it possible that what you perceive as too saturated is actually generally too red / yellow?
Are you saying that the ACI test print is identical to the same image on your monitor except that the skin tones are too saturated on your monitor? Or is everything on your monitor too saturated, but especially the skin tones?
