I came to a similar realization when I had to go back to a non retina macbook a couple years ago (after using retina). Other than the larger display scaling you really can’t tell or see the pixels at the distance you would comfortably use a laptop. Same thing with my TV. Its 1080p and I can’t see the pixels. I’d have to spend hundreds upgrading my tv and xbox to 4k and for what? It wouldn’t look any better 10 feet away on the couch.
