If field curvature would play no role because the AF gets always a sharp picture there would be no need for AF adjustments. Which I only do for center focus point. Field curvature does play no role when focusing in LiveView because here I always get what I see. The indirect phase detection could struggle very well in the outer focus point. Is there a focus point that far out of center in the Canon?
Talking only for Nikon. Their AF system has improved, I just hear from people who use / used both systems they always felt a little insecure with Nikon.
That leads me to the next question. In the sample shots, are you using LiveView or phase detection AF? My copy of the 24/1.4 was quite a bit off focus out of the box. Since I corrected that it's great, but before it would have been my explanation for focus on the wrong spot.
