Hard to tell. Well, it's not about graphics for sure. So I think it is better to say "supposed to feel like". 
The game has to feel alive. And it's not about realism too, it just has to be believable considering its own rules.

If you just look at current vr games, it feels like everything is made out of cardboard cutouts. There is no soul, even alyx, which many regard as the best vr game, is like that. 
VR is the ultimate artistic media, considering its potential, we are just jerking off.
