The corrections with the algorithm are always done at an “infinite” color depth.

So, does that mean from a 24-bit (R-8, G-8, B-8), the color-depth is increased to, for example, 48-bit (R-16, G-16, B-16)? [Details are beyond me and this laptop.] 😃

… in some cases “stressed” color may be a problem, especially with color crush, blown out colors, and compressed images, … you may have actually smoothed skin texture reconstructed by the color correction algorithm.

I looked at the original Blu-ray (posted previously) and saw that you were starting off with Lucasfilm stressed color®. Your regrade just brought it out stronger (mostly from the contrast, it seems) . .

Since it’s damaged to begin with, maybe a first step could be JPEG-DNR to the original, and then the regrade?
