Empirical? The problem with your reasoning is that you assume every difference can be quantified. According to how you interpret things, a CD should be able to sound as good as a live performance because the sample rate and bit depth should support it. Everyone knows that isnt true though.

Probobly because film is not as true as real life look and gives things a romantic glow.
