I was totally unaware that they morphed in the tank.
So you can spend some big $$$ on some frag and have it change into something else?
I am only guessing but it seems the ugly ducklings are the ones to morph more so. It could be because of lighting (more than likely is due to this). The more drab polyps growing on lower shelf walls, collected and eventually deposited into closed reef systems where lighting is totally different morphing not only the zooxanthillae but the shape of the tenticles as the polyp tries to adjust to the new lighting.
Can also go the other way I have seen several times. A HOT zoanthid goes drab due to high/low light and possibly poor water conditions, though in reality it would perish in poor parameters from overgrowth of fungus, algea, etc.
