why do you think the surfaces look less original?
The Smartphone photos make all the high points (stars, hair curls, tips of eagle's feathers, arrowheads) appear much lighter than in the first photo set. By Smartphone camera the coin resembles pieces that have been aggressively cleaned. Apparently that is mainly an effect of the camera and lighting since your "last looks" images show a more balanced coin.
I see what looks like fairly obvious light wear on stars, turban, hair above the ear, talons, and olive leaves. The images don't show much if any luster but if significant luster remains perhaps it could squeak into an AU-50 holder. EF-45 still seems more likely.
I don't see any evidence that the coin has been artificially toned; many early silver coins show similar dark, crusty toning with lighter halos around features like the obverse stars.
