There's no doubt a graphic designer can do more things better in this area. But a dev can acquire a skillset that is sufficient. I for example feel confident designing a frontend to the satisfaction of a customer, but I would never be able to put together a flyer or design an ad. As a comparison: While a skilled sculptist is undoubtetly better at his craft than a mechanic, the latter can take pride in finishing off a machine part just as much as the sculptist, and to an untrained eye, the parts display an equal amount of skill. Learning-by-doing gets you far. Actually investing the time and studying the field gets you further, but is more expensive.
