I've never had an omlette that was anything other than bland. Mostly because the egg is always overcooked and an overcooked egg is a horrible thing. Mind you, I've never had a truffled omlette, even after a week in the Dordogne, and I've always thought they might be wonderful.

Fried with a very runny yoke? Yes. Scrambled provided they are cooked very slowly? Yes. Poached with a very runny yoke? Yes.

Omlette? No.
