There could be a noticeable drop-off point at some percentage of near-realism, that ruins that effect.
Personally, I remember playing Half Life with software emulation mode. Then when I upgraded my computer and was able to run graphics-accelerated, it looked better but did not really increase my enjoyment of the game. A similar idea is true in making videos: what really matters is not amazing video quality. Instead, sound quality and story design is much more important.
