What you said may very well be true.
As long as people are satisfied with the results (as most seem to be) we have no reason to regard the quiz totally flawed. Yet it is just as you've mentioned, it overlooks some religions like the zoroasterism and some more peculiar philosophies. But then again, how complicated automated quiz can be made with reasonable effort?
I wish I knew more about religions to be able to say something more constructive about it, but as it happens I am, and have always been, somewhat secular individual I cannot really say nay or jay In the end, while I recognize spiritual experiences, I think they have lot to do with culture, communities and psychological experiences. At least according to my own experiences. About others I really cannot say.
