I also use a mac pretty regularly and a 1440p desktop. I was getting at the aspect ratio issue, which it seems like you were talking about first, before now talking about resolution (?). Yes, a higher resolution can fit more pixels. The absolute actual size in inches also matters though for how big the text ends up appearing.
I like the way one blogger describes a 1440p vs a 1080p: “A 1440p monitor will give you 3x code windows side by side and 76 lines of code. This is a pretty big deal. You might not realize it until you’ve tried it for a while but being able to comfortably have 3 editor files open and being able to view about 50% more vertical lines of code at a glance is huge.” ( https://nickjanetakis.com/blog/how-to-pick-a-good-monitor-fo... )
Though someone else mentioned they have 4K version, not just a 1080 version! That can work better with the right scaling. The rest of the laptop looks nice.
