DAI, GAI and SAI all removing detail

The project I am working on has a lot of detail that may appear as haloing, noise and/or blur. The problem is that as these different programs see this as such and remove it. Does anyone have any ideas how to enhance (preferably Gig) and still keep this detail intact?

I am working on a video where the frames need to be preserved and not necessarily enhanced, just 2x or 4x zoomed would be great.
