Have they fully implemented the Gemini-backed Siri?

I will say that I asked Siri some questions recently that I was pretty sure it would fumble and it answered directly.

“Does brown go with charcoal in clothing?”, for example, didn’t fall back to “I’ve found some web results. I can send them to your iPhone”. It actually answered.

It still has random nonsense regularly, but the “ask a question, get an actual answer” is new to me.
