Which Mac is 4480 × 2520?
The 24-inch iMac, introduced with the M1 chip and updated since, has this 4.5K Retina screen. It is 16:9, the same shape as a 4K or 5K picture, so wallpapers fit without cropping; the difference is only how many pixels there are.
A 4K wallpaper (3840 × 2160) has to be enlarged by about 17% to fill this screen, which softens fine detail. The exact 4480 × 2520 file is sharp. Displays settings show a smaller default size, 2240 × 1260, because macOS draws at twice the scale.
