I’d be interested in seeing more examples of the Rancor differences, if you have them. I like the frame you showed, but it doesn’t appear to be the exact same frame as the Sanjuro example.
Also, I know there seems to have been a great deal of difficulty making some of these Rancor shots color-consistent, possibly because they simply aren’t very consistent. In particular, there’s a one shot (Luke starting to hide under rocks as the Rancor lumbers into the frame in the foreground) where Harmy’s correction showed realistic skin tones for Luke, at the cost of the Rancor looking extremely desaturated. Sanjuro got the Rancor looking consistent with the surrounding scenes, at the cost of Luke looking unnaturally red-faced. I wanted to see where your correction landed with this one, considering your skin tones in general seem to line up better with Harmy’s color correction.
