If "it is significantly different from the sample or description" or "it has a problem that would have stopped someone from buying it if they’d known about it" or "it doesn’t do what the business said it would, or what you asked for and can’t easily be fixed." Then yes, it would qualify.

So a bad port that still used the same graphics from the original platform to advertise could be an issue. Or if it contained show-stopping bugs, it could be a problem. Or if the business drops features after you purchase.
