Of course that's true in general, although there is a bit of a gray area. With the use of mathematics (deconvolution) it's possible to retrieve details that are (just) not visible in the original data. For these techniques however it's necessary to know exactly the optical camera & lens behaviour. From what I understand of it, this is what DxO is doing. 

But this is different from print sharpening that we'e discussion here.
