Define "Better"
In the below example the 1920 image will give SIX TIMES the horizontal
resolution of the 300x300 image, but each pixel will only have half the
chrominance resolution. 6 x 0.5 = 3, so the 1920 image will still have
THREE TIMES the chrominance resolution of the 300x300 image.

a 300x300 4:4:4 image is not better than a 1920x1080 4:2:2 image.
But the individual pixels of the 300x300 have more color information EACH
than the later image. And you would get a better key from the 300x300 image.
