That's actually one of the reasons I really like Torisan corruption. It doesn't have to give us a big palette change to let us know 'yes, they're really corrupted now'. (Also why I can like but never love Mega W corruption. Towards the end it really is a different person, like they found a different actor for the same role and said 'aight, she's that far gone now'.)There's going to be a tanned-Aura appearance change, which may or may not be optional since not everyone likes it. I wouldn't expect any significant Roya appearance changes since there are so many CGs that would then need new variations.
IMO anyone who's progressed far enough down the corruption path knows how far Aura is from when she started. She doesn't need a tanning bed.
