@afre so you’re saying the inside of the nose doesn’t look clipped red to you? Hmm it might indeed be my monitor. I have an Acer which I calibrated, but I suppose I shouldn’t rely too much on it or put too much faith into it 
As for BruceRGB I suppose it distributes the available colour values differently staying away from what looks like highly saturated values in ProPhoto. Also looks on average a tinge brighter. Hmm.
Another thing to mention is, I find changing the Rendering Intent in RawTherapee, whether in the Colours tab, or in settings, does not make a noticeable difference at all 
I am running version 5.0-r1-gtk2, haven’t updated to another due to the gtk2 aspect. I need to upgrade my Debian box to something more gtk3 friendly but I thought Rendering Intent wasn’t something that was broken in any version 5+.
