> Yes, this is why photographers who avoid postprocessing because they're "purists" who like "unenhanced, natural images" sometimes deliver unnaturally bland images. The visual system phenomena at play are high dynamic range, simultaneous contrast, chromatic adaptation, and perceptual uniformity.

I know next to nothing about photo processing but I would assume that because watching a photo print in a random environment is not the same thing as being immersed by the scenery and lighting in the photo, the perception is influenced by that very fact and reproducing photographer's own impression of the scene purely by means of physically correct measurements and their reproduction in form of a picture is impossible; ergo, alterations are necessary.

That's exactly what he's saying.
