Well, if that was your problem, you shouldn't have asked how I identified a specific one from it's appearance when there are "only four general types of galaxy." Only once I said so did you move the goalposts and say that the appearance didn't mean anything.
I'd be inclined to agree with you if they'd used a photo of the Orion nebula, or a picture of a moon of Jupiter for a nearby planet or some other obvious corner-cutting, but given that it's an appropriately distant galaxy, and they even did the rather trivial touch of reversing the image to represent seeing the far side of the galaxy, there's enough standing to accept that was where they were, in as much as it means a damn thing, anyway. Besides, they went to enough trouble to use one of the real Pegasus galaxies, and even showed the right one for the distance they quoted.
