Most people, i.e. people that are not on HN, can't tell the difference between 27" 1440p vs 4k monitors, unless you ask them to look really carefully.

Lots and lots of people use 15.6" laptop with 1080p screen and are perfectly happy.

Every time I see people talk like this, I have to wonder who it is for.

All of Apple’s operating systems are designed for high PPI displays. There’s no font hinting, no subpixel AA. Apple decided long ago that a high pixel density is a baseline requirement for any device they sell, including computers, since the 2010s. You can use a low PPI external but it will not look good.

Given that the smartphone industry also adopted high PPI displays as a minimum standard, it’s actually the external display industry that is the odd one out here. Low PPI displays should have gone the way of CRTs, but they cling on.

Game consoles, which constitute large deployed numbers, generally have gameplay at lower resolutions.

It's incredibly easy to see the difference. Cell phones used to have low-DPI displays, and I don't think you can find anybody who wouldn't be able to easily see the difference.

Retina displays have been around for more than 10 years now and are just much better than low-DPI displays. Especially for text and user interfaces. For movies or gaming it doesn't matter so much.
