As a former professional designer (and current improvisational musician( myself I would even come at it from the other direction: There is no true originality to begin with. Everything you do borrows from somewhere else, except maybe the things you do by accident.

But there is still a difference between a designer who blatantly slaps an existing aesthetic onto your project and a designer who tries to come up with a suitable look from first principles.

Design isn't styling, it is the visual organization of information with styling. So unless your information is the same the outcome will differ anyways.
