...Micro-contrast and near focal plane OOF characteristics. You're not 3D blind.

So background separation from the subject is not the lens 3D-pop being referred 
to.
This sample photo from a canyon 180mm macro has 3D-ness but not the pop.

Longer focal length lenses would then be more likely to create 3Dness.

As to "visible on the camera LCD" I question that. I have noticed, at leas on 
the Sonies, that the image can sometimes have that over sharpened halo, 
implying that the displayed image is sharpened. It is even more obvious in the 
EVF.
