Tekken's ground textures don't look that good either. Not many fighters have good ground textures if they are 3D fighters, walls are usually as good as they get and they even get shafted. Keep in mind that LR on PS4/One are ported from PS3/360 and at higher resolutions, not too many things were upgraded during the port (looking at the Dishonored port as well). If you had to port another copy of the same game for the nth time you wouldn't want to upgrade everything every single time just to make an audience and users that are more focused on the action of the fight rather than "that first spot on the ground looks like shit, I am distracted." The whole thing is like costumes to serious competitors while playing, could be playing stick figures and it wouldn't take notice until "Get Ready" and "Winner" before you remember that you chose the figure with the orange hat and not the purple one. I sure as hell don't pay attention to outfits and arena appearances until matches are over and remember "Oh yeah, that's Fork's outfit I picked for Leon and these dst particles are obscuring the surrounding environment."
Just take it as it is and live with it, the nitty gritty details aren't there because that is not what the developers expect you to look at based on their target audience. If you look at a lot of games that were made for 360/PS3 and the textures aren't flashing, vibrating, have something like grass protruding from them, or have some special effect going on and aren't a specific landmark chances are the textures aren't that great. There are lots of ways to hide textures, some companies just make it difficult to notice. Even if you look at a lot of modern textures there are still a big number of games that the textures aren't where they could be.
