Don't forget that PZ's sharpening makes the difference more pronounced (in my opinion), since sharpening does not affect every unsharpness level to the same amount. So, on lower res. sensors sharpening lifts so-so results more than on higher res sensors.

 

That isn't entirely true. We sharpen on every platform till a defined (identical) threshold is reached in Imatest.

This doesn't equalize everything but it evens out some sensor differences.
