Have you done side-by-side comparisons? I have compared the picture quality of 2015 MBP vs 2020 MBA vs 2021 MBP (16").
The 2020 MBA and 2021 MBP are pretty similar.
The new cameras have better low light performance and less noise due to pretty agressive smoothing. The consequence is that the picture lacks any detail whatsoever. The image from the 2015 MBP is sharper than the alleged 1080p image from the 2021 MBP.
With the smoothing my girlfriends face looks like she is wearing heavy makeup. My beard looks like it was painted on. In low light there are weird artefacts and glitches (especially in the area around my eyes, probably due to the ML algorithm).
Now maybe on a Zoom call this doesn't matter, if your face is just in a little matchbox-sized box on the screen. But on full screen Facetime calls the lack of detail and low resolution of the MBP webcam is very noticeable.
