Bluntly Kvally... you won't spot nearly enough of a difference in appearance on the title to call it superior.
The benefit is slightly higher FPS (40-50 for XB1 is still no slouch) and better aliasing on the PS4. But as you have seen, it isnt all that distracting on the XB1 version anyway.
Eurogamer even states the graphical assets and effects are identical on both versions.
I think you may have asked a loaded question, and the response will quickly devolve into another spec pissing match with no good end
