I get what you’re saying and don’t think he should be completely scrubbed of that look. But before, he had almost a fluorescent looking magenta tone, especially on the lips (which everyone on the 2004 master has). It’s more reasonable now.
I’m not sure what the correct contrast is. But it probably varies in the different scenes of Tarkin in the same rooms. So educated guesses considering (but not depending on) quality 35mm scans might be best.
