I hate to be a naysayer, but I’ve found these grades to have a somewhat unnatural colour pallete. It’s common in digital grading - the skin tones have a sort of apricot hue and you can’t unsee it. Having said that - it’s much better that you’ve brought the levels up and boosted contrast as the 4K83 was far too flat to begin with. The latest 1.3 minimal DNR is much improved in this respect, and retains more accurate colours.
I personally feel the skin tones on many of these releases are unnaturally pink, but we all have our preferences.
