Partially mirroring my late GitHub comment: not a fan; the whole station turns like 40% darker as well as more dull, since the new floors seem to trade natural gentle discoloring and color smudging for flat coloring and a group of dots on each quadrant. With the darker tiles, places like Medbay/Science become gray rather than white, and the half-white-half-colored tiles lose a lot of vibrancy and contrast. The change also messes with the general floor-wall contrast difference, not sure if in a good direction.
One place that does look a bit better is the kitchen, with the black-white tiles becoming a bit less straining to look at, though that's about it.
The maintenance plating has the opposite problem, being very smooth and shiny - almost cleaner than regular floors - which is odd for what's supposed to be a comparatively seldom-used, run-down maintenance tunnel with dirt and cobwebs galore.
I'd also agree that having the dotted floors everywhere is a bit much visually, imo the new dotted variant should indeed be a separate tileset and be used somewhat sparingly; the dots also give the floors a slight "high-traction" feel they aren't supposed to have (as that's a separate unique tile type with actual gameplay effects).
