Which is the iPhone 11

I ask this because the difference to me is hardly any. I have been taking low light pictures and they are just so grainy indoors. The point and shoot with this camera in low light is atrocious, I get that pro mode, raw etc can be good l, but cmon man flagship phone barely out performing a iphone11!! Genuinely, is there something I'm doing wrong or is this just the way this camera is?
