But the AI should not have learned to apply a Gaussian deconvolution kernel. If anything it should be applying a lens-based bokeh kernel instead. A true lens blur does not behave like a Gaussian blur.

They don't get an exact reconstruction of the original image. What happens if you apply Gaussian blur and then try to undo it with a bokeh kernel?

A mess.

A mess like in the OP https://imgur.com/ULVX933 or something worse?

You certainly wouldn't be able to recover any detail this way (in fact, deconvoluting Gauss after taking a photo of the picture displayed on a computer screen won't give you any kind of sensible results either - try it yourself).
