I’d bet there’s a toggle that dramatically increases opacity or eliminates transparency entirely while keeping the shading and gloss. If it exists I’m sure it’ll be popular.
Given the huge change and sensitivity to accessibility I'm going to guess the opposite -- it will be designed to look nice without transparency.
It’s simply a matter of “which settings would MOST of our users want enabled by default?”
I do agree that the accessibility settings can make ios pretty ugly though. It’s a real shame. :(
