No it's not.
Pop is by definition written within boundaries that are geared towards widespread commercial success, ie popularity, whether it achieves this popularity or not. I suspect you have a wider definition of pop than I do: in my mind, whenever anything veers away from these boundaries or formulas and tries to chart new waters outside them and outside the thrust of mainstream tastes, then its no longer pop, despite any success it may have. I don't think of the later Beatles albums as pop, for example. Pop is the generally mediocre stuff off their early records that financed the experimental brilliance later. You can have good pop songs, but ultimately there's only so much you can do within those boundaries. I don't subscribe to the claptrap about 'polished pop gems', which is more pretentious than most things I've ever said: sometimes you can't polish to the three and a half minutes, if you know what I mean. The best music breaks boundaries, and pop has more boundaries than any other genre I can think of.
