Even that's fairly meh, even in the center. That's worse sharpness than the 100-400mm II with a 2X TC attached. I wouldn't expect it to match L glass bare, but to be worse than a zoom lens with a 2x on it is a little disappointing for a prime lens.
No it's better than the 100-400 II + 2X TC.
These are the new type of MTF charts which account for diffraction. The center sharpness of the 800 is truly diffraction limited.
See how the 100-400 II with 2X TC performs in the same type of MTF chart here:
