It’s closer to 1080p

Especially when comparing 24” 1080p to 27” 1440p. 

4K is a much bigger jump. 

1440p is not halfway like people think it is.

I have a fullhd, 1440p and a 4k monitor. What you said is technically true but it's quite not like that in practice. From my subjective experience, jump from fullhd to 1440p is a lot more significant than a jump from 1440 to 4k. To me, 1440p is the sweet spot where things look sharp but the performance cost is not too bad. Same cannot be said for 4k.
