I was trying to take a passport photo, and one of the requirements is "has not been touched up". But when I took the photo with my phone, I noticed that it had been very helpful in touching up my face by removing almost all of my wrinkles and made my skin nice and soft. Even with all "enhancements" off. This was on an Samsung S10, I tried with an iPhone SE, it was slightly less visibly touched up, so I used that, but still definitely had a "beauty" filter built in. It's probably implemented in ASIC so you basically can't turn it fully off.
