I'd suggest there is more to it. While each photosite is 8.2 micron, they are part of a 16.4 micron Bayer matrix.
De-bayering is never kind to point sources. While one can post -process in a number of ways, if the image is undersampled (eg square stars) no real increase in resolution can be made unless the focal length is increased (ie oversampled)
