re: Yes

The Soviets brought back a few grams of Moon soil too with Luna 16, 20 and 24!

And those samples were s informative as the others from Apollo.

It's not the quantity that matters.

So far, only several kilograms of Lunar rocks have been studied.
But that is often all that's needed.

Besides, a few grams are much better than none at all.
