What are these features that can't be measured?

Plenty of people who test monitors also compare things like color coverage, brightness, latency, contrast, viewing angles, etc, etc, etc. If you mean the entire monitor, they generally also cover things like how the display swivels/mounts among other things.

Brightness and contrast are also gamed to hell and back. You have to go to some very specialized review sites to read about contrast at low brightness (lights off software development scenario, or maybe even lights off gaming).

I must admit I've sometimes seen a description of how wobbly the monitor is when you hit your mechanical keyboard like it's stolen your car and killed your dog. Veeery rarely though.
