I think you indirectly are right: Pop science News articles that have “reality” in the headline about topics like string theory tend to have “artistic impressions” with random CG art just like this, and I bet that’s what the AI based this on.

But the more direct answer is no, that’s not how Calabi–Yau manifolds themselves are generally illustrated.

That’s a great observation. I was only thinking about the “infinity twisting around it’s self” vibe
