You're probably right, pretty much everybody who renders from digital elevation models ends up deciding it "looks better" with an order of magnitude exaggeration. Who's to say they're wrong? Years ago I advocated for adjusting the colors of Martian images to simulate terrestrial illumination, on the theory that would be the most efficient presentation for terrestrial eyeballs. I.e., don't throw away a geologist's lifetime of training visually recognizing minerals just to be a technical purist.

You might not want to use that video for navigation, but for giving a Terran a better visual sense of an alien planet, three thumbs up.
