I think that you are approaching this from a strange angle. Previous claims suggests that it is impossible to recover "true sharpness". Now, as long as true sharpness is not clearly defined, this could be taken to mean anything, but I think that for most sensible interpretations, this is wrong:

1. An image that is perceived as "blurry" can, in fact, usually be processed so as to appear "less blurry"

2. A camera system with a given mtf50 can usually be processed so as to have a higher mtf50.

In both cases, there are practical compromises to be made, and deconvolution is far from a solution to all problems.
