1. TV sizes are getting bigger and bigger. You mightn't notice the pixels at the size of your current TV, but your current TV might be considered small by the standard of increasing screen sizes.
2. You mightn't be able to see the pixels on your 16" 2k screen or on a 4K TV, but your eyes aren't the only ones on the planet. To my eyes, 2k is old news; my 13" has 1600 pixels vertically. My left eye can barely see anything thanks to keratoconus, but with both eyes open I can still discern the difference between 720p, 1080p, and full 4K content on my TV — mainly in games and Blu Ray movies.
3. You don't need to rewrite every single application to support HiDPI displays — Windows already has scaling baked into the OS (and has for years), and the majority of apps support the feature with no issue; macOS has had Retina display support since late 2012 and only apps ported from Linux exhibit any weirdness.
4. All of the Galaxy phones have had OLED displays standard for years, long after 720p was considered a high resolution for a phone (back in 2011). Even some of the non-flagship models have HiDPI OLEDs and aren't particularly expensive.
