It may be the similar but as they say, a picture speaks a thousand words, the visual features that a CNN might pick up could be something completely different than the features someone could think of. It is all about data representation. Hypothetically, the data representation shouldn't matter, but I think it is like viewing the optimization surface from a different angle, it is possible to get something different out of it.
