Yeah it ain't bad, but my desktop has 4K@15.6", which is around 280dpi. Actually smaller gap than I thought, but an 11 inch display is going to be used closer which amplifies it.
Brightness and vividness of colors is a huge plus though, OLEDs are amazing. I love them. But it's gotta be 4K.
I still use font size 14+ even with a very close to face small display. My belief is that higher dpi isn't useful or necessary. I can read font size 8 on a low dp display fine & not complain.
If your display isnt as high dpi as you want, there's almost always plenty of font sizes down you can go & still be fine.
Not tiny fonts. Normal sized fonts, but cleaner. More pixels.
I like 4K because it's an easy 1080p display but with enough pixels to make everything look way better. And everything divides evenly with a perfect 200% scale factor so I don't get any weird rounding errors.
On Android this is much, much less of an issue due to their DIP system, but more pixels still = better, imho.

Maybe I am just cursed with above-average vision.
