Disabled Person Question

So I am legally blind, but I can see clear detail at a very close visual range. When I play games, my face is about 6-7 inches from the screen, but everything is clear.

Because I have to sit so close to my monitor, it doesn't make sense for me to have a screen any larger than 23-24 inches.

I'm building my next rig and so my question is, does it really make sense for me to invest in 1440p (vs. 1080p that I'm on now) if my monitor size needs to stay at 23-24 inches? I know 27 inches is more ideal for 1440p, however, would it still be worth it for me to invest in the higher resolution, since I might still see a noticeable difference at a close viewing range?

Probably a hard question to answer unless you have a visual impairment like mine.
