Those screenshots are from game mode, not editor. Finally you can see a quality close to the one on the screen. Anyway I would say that in the scaled screenshots at 1300x800, the 2Kx2K textures are not appreciated at all.
First of all, some of the problems with tesselated concrete in vanilla game. Floating assets, lowres decals, parallax glitches, tesselation not alligned with cracks mask, etc. In my opinion, this concrete floor don't need tesselation, it's not real.
