Thanks for the link! I didn't mean Dune looked intentionally fake, but I think there was some cohesiveness in the creative decisions behind the VFX, the cinematography, the set and costumes designs, the editing, etc. that intentionally creates an enhanced dramatic aesthetic, along the lines of what you might see in a Baz Luhrmann movie.

As per the original author's point, the shot included from Dune looks like something out of a fantasy world, whereas the shot from Lawrence of Arabia just looks like a dude walking around in the desert. But I think this difference was intentional and goes deeper than just CGI
