If it were just that "higher number sells better" reasoning then it wouldn't make sense the density increases had a pretty hard stop after ~2014. Same with why 8k TV hype died down but 4k TV became mainstream - it's about the genuine limit for a typical person at typical TV viewing distance unless they have an absolutely massive TV.

I always thought Samsung had a clever approach with a toggle to just render at the lower resolution if you wanted the lower rendering load. Then you still only need to develop 1 cutting edge screen with all of the latest improvements but it will please both use cases well as the cost overhead of shipping models 2 separate screens would.
