It's a lot of CGI, but done in realistic ways.

The person I replied to said it was "mostly real". Lots of CG is done in realistic ways but people pick and choose what they decide is good based on the movies they already like. Fury Road has somehow become an example of "doing things for real" when the whole movie is non stop CG shots.

A lot of the examples from the article (which is a very good article, thank you for linking it) were mostly about paint-outs, color grading, or background elements.

No they weren't, there are CG landscapes, CG mountains, CG canyons, CG crowds, CG storms, CG cars, CG arm replacements and many entirely CG shots. It's the whole movie.
