I mean, what I’ve noticed about real life is that (with Caucasians at least) skintone can really vary. Sometimes it’s a little more peachy/orange like your corrections, and other times it’s slightly more pink/red like the original. Neither look unnatural to me, which is why I say it doesn’t seem like it makes much difference. But hey if it makes that difference to you, that’s all that matters.
Yes I know, sometimes you come across young people with very reddish faces, almost looking sunburnt but its just their natural complection, nothing to do with staying in the sun too long. Where I live it’s common to see older people with more reddish complections. With the TFA regrade the main aim was just to maintain fleshtone continuety with the other Star Wars regrades i’ve done, not make any commentary on what is natural looking fleshtones.
Here are some shots of Harrison Ford though on set that suggest his face wasn’t as red as suggested on the blu-ray (the first shot can be directly compared to some of the TFA screencaps i’ve put up, its taken from the same scene):
