Riddle me this - why would you want to disable something that increases usability of an application? (Yes, this is a loaded question - I never said these features are bad, just that usability and accessibility are sometimes at odds with each other.)
If they did, they'd just be called "features".
Disabling high-contrast display makes the colors more aesthetically pleasing.
Disabling large-print text allows you to view more text on the screen at one time.
Why don't you run your apps/OS with every usability feature enabled? Share your reasons.
Other than that, is enabling/disabling any of the aforementioned features ever a question of aesthetics?
I’ve installed a utility on my laptop that supports “sub-zero” display dimming for nighttime use because monitors are now over-optimized for max brightness, with min brightness being retina-searing for eyes adjusted to a dim room.
