iPad Air camera quality

I just upgraded from an iPad Air gen 3 to the 5 and I noticed that the camera quality is awful. It’s not that iPad camera quality in general is just bad, my old iPad was totally serviceable. The new camera is incredibly grainy and all photos come out looking dark regardless of lighting conditions or whether the flash is on. I called apple support and they couldn’t find anything wrong with my camera, and regardless it doesn’t seem broken just really low quality. I have to assume apple started using worse cameras, but I can’t work out why. Does anyone know what is going on?
