Whether it 'looks' right or not does not change the fact that this 'detail' is software invented and not optically captured.

Aliasing isn't software-invented, it's spacial frequencies mirrored about the Nyquist frequency.

The software 'fix' to this is to invent 'detail'. How else do we get the appearance of complete detail beyond Nyquist?
