You could say the same thing about vanilla, for which Cooks Illustrated was infamously not able to triangle-test a meaningful preference between artificial and real in a baked goods panel (IIRC, the Milk Bar cookbook went a step further and specified recipes that only worked with artificial vanilla). Sometimes, the artificial ("beer-grade") version is a legit advance.
A big problem with truffle oil is that it's too easy to overdo it, which is something you're less likely to do with a $200 black truffle. It's also too easy to add truffle notes to things that aren't really improved by truffle notes. And those two problems compound each other.

It can work pretty well on french fries, though!
