It’s a distinction without difference as far as the market is concerned. Your question was just flamebait. If other manufacturers saw how important this would be, and if Apple had zero involvement with the display development as you claim, then those other manufacturers should have bought exclusivity first.

Instead, I’m sure Apple was involved in the design and development. It’s not a coincidence that the display just happened to exactly quadruple the resolution of the iPhone’s previous display while maintaining the exact same size.

Either way, nothing useful can come from this topic diversion.
