I'm not underestimating. Really, but practical experience tells me that the difference in colour between a good colour photograph taken on a good camera and real life is actually quite small and subtle.

Sometimes I read a post where people make out that a photograph can't be used a reference because it's not RL.. It's pretty close!

Anyway we should probably be comparing video cameras to the eye. No exposure time involved.

No. I'm afraid you don't understand the basics of contrast perception and display.
The image in the default game is already at your monitor's contrast limit. Load your images you've posted into photoshop and have a long good look at the histograms. The default shot has just a tiny little headroom at the bright end, and blacks are black.
The image with increased contrast is just darker. You dial in more contrast, but your monitor can't display that, and this transformy the complete instrument panel into a pitch-black mess. You'd have to switch on cockpit lights to read your instruments at noon on a sunny day, and that's something you just don't have to do normally IRL.

Video cameras, just like photo cameras, have exposure times.
