Kind of depends on what features you are looking for.
Accessibility features for visually impaired individuals are very similar across all recent models of iPhone. I would not say the iPhone 12 Pro is better than any other iPhone to date like the current iPhone 15 Pro or Pro Max, as the features on them are very similar or identical in most cases. Not sure why anyone would single out the iPhone 12 Pro for this.
You can read about the Vision specific features in current iPhones in the following link.
Most of these are available on any iPhone running iOS 17, and would not be limited to just the iPhone 12 Pro.
In fact newer models may have new or better features than the iPhone 12 Pro. Though in general they should be very similar.
