I've never come across any peer reviewed data that suggest perfect fitting is better for tone.
Piezo's bring up a good point though. In fact it's not uncommon to purposely make the bottom of the saddle less then flat to make the pickups sound full across the strings. Much of that is due to the fact that a bridge might distort over time and so the bottom of the saddle slot is actually arched. I suppose one could argue that the correct way to fix that is to re-rout the saddle slot but in 5 minutes I can fiddle with the bottom of the saddle and get it just right too.
