This image was created with the use of Quixel Megascans (their 3D scanned asset library). Can you distinguish which assets are imported from the library after a quick look -
so i would say this is not a fair question. 1. it does not show photorealistic nature of 3d scans (3d scans can look way better) also u ask to compare say trees and mushroom while tree is out of focus - what comparison is that? very biased.
on the other note - might be this might be of some interest for you - https://3dideas.wordpress.com/2019/11/14/3d-scans-and-asset-flipping-in-game-dev-world/
