Bad video quality at night (S26 Ultra)

I recently switched back to Samsung (S26 Ultra) after 4 years of using an iPhone and the videos I take a night are very bad in quality compared to the videos of my 4 year old iPhone. I'm sure that I could make the video recording at night much better if I just tweaked some settings but I'm not sure which ones. I tried turning off the HDR10+ but it didn't help, maybe i should try lowering the video quality next.
