Its likely the S25 did well because it knows what the moon looks like so it fakes the details.

Since the Galaxy S21 series, Scene Optimiser has had the capacity to recognise the moon as an object. This means that the detail enhancement engine, a key feature of Scene Optimiser, is applied to photos of the moon.

When you take a photo of the moon with your Galaxy device, the camera system uses deep learning-based AI, along with multi-frame processing, to enhance details.

The OP has not said anything about turning the relevant options off.
