Do all live-bearers get prominent gravid spots?

My yellow guppy fry were easy to sex pretty early because the females quickly developed noticeable gravid spots. I don't remember seeing that on other live-bearers, even light-colored ones. I haven't owned others though; I've just looked at them in stores. I separated my guppy fry as soon as I identified who was who, but although the spot is bigger on guppies who've given birth, it's obvious on all of the females. I'm just curious if other light-colored live-bearers are the same. Thanks!

If they're kind of translucent like that guppy, platies and swordtails are the same way. I've had various color varieties of both over the years. The more wild-type and pale color varieties showed that easily. Darker colors and less-translucent ones, not so much.
