I would say yes and no. Yes, obviously the renderer is there but at the same time it's only doing what it was told to do. Taking Unity and Unreal as examples, you can make something look plastic, cartoony, realistic, a mixture, or really anything you want. Usually there will be art director(s) (or a someone with a similar title) that make sure the art/graphics stick with a certain look and feel so I would put the blame more on them than the engine.
