honestly overall just to set it in stone, and also the person i'm replying to is very non specific and it really honestly applies to everyone who thinks their computer has this "problem". this (bad MacBook camera's) is very normal and if you want to know how i know and why i am saying this with so much confidence, it is because if you actually run windows on your MacBook with BootCamp you will notice that actually in windows the camera is even WORSE, like, honestly by far, and i would show you but i can't because i'm a little busy right now but honestly i may later if i remember, and i personally declare this as the final decider because actually considering how much i use my camera "unfiltered" in apps like discord, zoom (without the filters on), etc, i can most definitely say that the camera i saw in windows compared to MacOS was definitely worse and in fact MacOS seems to actually have built in "filters" itself, for example, open an app that uses your camera on MacOS and stand ABSOLUTELY still, it will start to denoise until you move, now in windows, do the same thing and well, if you don't want to check yourself lets just say not only is the camera slightly darker, it also doesn't have denoise (in windows), and honestly just overall the noise is by far 10x worse in windows and also don't worry, yes, i am noticing after posting this that this ending is very odd and abrupt, idk what to do about it and gave up
TL;DR, bad cameras with the MacBooks is actually not only expected, but honestly normal sadly, and if you didn't read above but still want to know why i have this conclusion, if you go into windows to get the true, ACTUAL raw camera feed you will notice that it is actually much worse than the already bad camera you see in MacOS, and if you want to check for yourself you can use the built in app called BootCamp and set up windows and see for yourself just how much processing MacOS does to the camera that you aren't really told about, and even i myself have never found any article, Apple official or not, that has the same discovery which is kind of surprising
