The "hard requirement" is just multi-frame noise reduction, which has been around for a lot longer than the AI/ML hype wave, and has always had a risk of producing similar artifacts to this one.

Ya, I don't think anyone has been using ml/ai in camera phones up until the last 5 years maybe.

But it does seem like they have quite a few high tech algorithms at play. More than just multi-frame noise reduction.

Multi-frame noise reduction only gets you so far. Rotating objects for example present huge issues and result in their own artifacts. In the end there isn’t a free lunch, any system that improves resulting images is making trade offs.
