It doesn't matter if a game has perfect particles/lighting/physics/etc. As long as it renders at such low resolution the image quality will always be ruined by
aliasing artifacts like shimmering, flickering, pixel crawling, etc.
Temporal stability is easily one of the most important factors for a game's IQ. In many games even 5k plus TAA is not enough to eliminate all temporal aliasing, let alone the joke of a resolution that is 1440p.
When you sit 2.5' from a 32" display, the display needs to have a resolution of 5136x2889 or higher for it to be indiscernible, assuming a 20/20 vision.
Here is a calculator that gives you the exact resolution you need for your display size/viewing distance.
More importantly, display resolution and rendering resolution are two separate things.
For example,
here is a natively rendered 1440p image vs. a 5k downsampled to 1440p image. I can see the difference between the two on my 6" 1080p phone.
You do not need a large display size or a short viewing distance to enjoy the benefit of rendering games at higher resolutions.
