Well, you can clearly see (in the lab images) that the center is very snappy now (the borders/corners remain muddy).
This can be either due to the new coating (higher contrast) or because better centering.
The official MTFs vary slightly at the extreme corners so something has changed (albeit just a tiny bit).
