But what if the pixels can't 'see' the outer parts of a large aperture (because of 'pixel vignetting')?

If that has any impact at all it's minor compared to the impact of a larger absolute aperture. I've seen this with the fast Voigtländers, where stopping down from f/0.95 to f/1.4 has a small impact on shutter speed but a very noticeable impact on DOF.
