I think a lot of times the photos you see the most of a given morph are of really nice specimens of that morph. If you do a Google image search for "pastel ball python" you get a whole bunch of pictures of nice pastels, but if you look at the adult pastels for sale in the classifieds, most are pretty sub-awesome.
Just as there are animals in the top 10% tier of appearance, so there must be animals in the bottom 10% tier as well, and those might look "different" because they aren't average-looking. Honestly though, I have seen plenty of bees that look like that. I think you just don't see their pictures all over the Internet as much as the flashy ones.
