I saw the sample of the WD3 version of S23 Ultra firmware being tested, and it seems that the photos at night have also improved.

Can Samsung squeeze out better performance out of that 200 MP sensors? Maybe, maybe not. We wouldn’t be surprised if the improvements try to tackle the performances of the ultra-wide and telephoto cameras. These struggle more with dark scenes, due to their physical limitations (they are still OK, but nowhere near that main camera).
As far as when we could expect such an update to come out — we can’t be certain. But there’s no rush — we are enjoying the S23 Ultra camera as it is and we’d rather have Samsung take its time before tinkering with it.
Weird time we live in — when the hardware camera in your pocket can suddenly change the way it performs due to an update that it receives wirelessly (and, depending on your settings, without even asking).
