It's the same thing with the webcams on the M1 Macs.
Comparing my 2015 Macbook Pro and my 2021 Macbook Pro, I can say that they both have crappy webcams. The 2015 has a somewhat grainy, high contrast look. The 2021 webcam has extreme smoothing applied, to the point where my facial hair looks like it's painted on. The result is that my face always looks blurry. There are also weird movement glitches that are probably caused by temporal smoothing.
From a distance, the pictures from the new webcams look better. But up close it's frustrating that my face is always blurry.
Webcams still remain an issue on laptops because the space for them is extremely limited; the iPhone 13 Pro camera has tons of z-space to work with, while the Mac has to keep it thin to continue to look like a modern laptop and not a 2003 thinkpad.
