No, I've studied a fair amount on experimental design and inference, so give me a little credit and stop with the "lols."
Yes, they perceived a difference. Ask yourself why. Is it because people like to imagine differences where there are none (I suspect this is the conclusion you would prefer to draw). No, it's because the "experimenter" set up a situation in which the "subjects" 1) expected to see a difference, based on the previous trials and the experimenter's instructions, 2) believed there was a difference, based on the previous trials and the experimenter's instructions, and 3) knew that their task was to find the differences (not the similarities); success meant distinguishing among the three and assigning them the right labels. Nowhere in this setup is the notion that all three are really the same. In fact, the experimenter set it up so that the expectations and requirements of the situation practically demand that the subjects find differences, even if they have to manufacture them subconsciously or base them on random variations (which is what they did).
It's a neat trick, but it leaves you nothing to infer about the real world. In order for this to "speak volumes" about anything, you have to show how this situation is analogous to anything in the real world. "People see differences between X1 and PS4 when there aren't any," I can hear you say. But that's not what happened here -- people saw differences in three PS4s. The only inference you can really make is that when people are led to believe they are presented with three things that are really different, and the task is to find those differences, they will do their task, even when the experimenter makes all three things equivalent. That's no big surprise to me. Given the conditions and the way things were set up, of course they "perceived" differences. You would, too.
Otherwise, it's an amusing little trick but not much else. I suspect that you'd like it to mean something that it doesn't.
If I were you, I'd hang my hat on the difficulty several of the Gamespot editors had with distinguishing Xbox and PS4. That's something you can draw a clear inference from (well, except for the sample size, and the fact that two of them got it right).
