I saw a thread on reddit about tinkering with individual graphics settings to "fix" the 7.6 changes. The initial change offered there didn't do a lot for me, so I went back in myself and ran Theron's date night (with its wacky lighting) a few times.
Spoilers: They can't be reverted or 'fixed', but they can be toned down. The suspension of disbelief thing was killing my joy bad. I play on Ultra, so this is done with other settings at max; if you play on lower settings, the payoff might be less, but it'll still help.
Here's a screen shot with the 2 key settings outlined in red and yellow: Character Level of Detail and Character Texture Atlasing. Set both to "low."
The wrinkles and eyebags are 3-D textures; light plays off of them, so you will still see shadows and creases where you did not before, but they are reduced by essentially 'blurring' the character. As mentioned before, this is really evident for people in neon environments such as Mek Shaa and Nar Shaddaa; you will always see the creases/bags and their artifacts there. However, in most other direct light environments, the severity is reduced. Eva still has a few lines and wrinkles, but they're not as crepey as they were before. It's like when you have to smooth out your concealer at lunch because it got into a crease during the course of the morning.
Some good news for Chiss and Miralan: according to my Fria and Spouse's blueberry, this does smooth out some of the color weirdness. Again, because the devs changed the textures of the characters, there will be some that remains, but it is less intense.
My Torgruta Padneema still looks pissed as fuck, so it doesn't fix everything. No, she wasn't always like that, just for clarification. Hope this helps someone who didn't like how their blorbo turned out after the update. It won't be the exact same, but hopefully it's less of a change.
