Like already been mentioned by me a couple of times, there are also females that won't show a gravid spot. What's going on when a female doesn't show a gravid spot? It means that at the spot where usually the gravid spot appears, there is a dense concentration of chromatophores (color cells) in all three skin layers. Which makes that spot not translucent. So, no gravid spot will be seen. A progressing pregnancy won't change anything.

Okay, I'm confused (no surprise there), but is this the same fish in both photos? Just with a more darker coloration?
I feel like I need some more context for this to make sense to me.

I've also noticed guppies with clear, yellow, red, and orange gravid spots still drop fry normally

No, these are two different females. It's just to show that not all females will show a gravid spot no matter wether they're pregnant or not.

The ones you mention do have a gravid spot. And yes, the colors may differ. That's got to do with the fact which base color the fry will have (grey, blond, golden, bronze, asian blue, white, copper, nigrocaudatus). And the mood of the pregnant female can change the color of the gravid spot.
As I've told frequently, the gravid spot itself is just a more translucent part of the skin. It may contain some color but with a very low density of the color cells. This enables the see thru part.
 
I had a female guppy who I bought BECAUSE I couldn’t see her gravid spot and therefore thought she was sterile.

Alas.

A week later, while she was still in QT, I was proven very wrong. 💀

And now you know that it's got nothing to do with being sterile.

How many batches of fry can a mutt guppy have in their lifetime? How about wild types? Kept track of a single female's total progeny?
