The hand on the right looks quite different, stretched.
As usual, images have very little information. Could you attach an example file with the displacement texture, perhaps with a render from ZBrush, so I can understand what you see and perhaps place some notes on the render that are important to you? I assume we all have our ideas of how things have to be.
So far, I think it is safe not to use a SDS-object and RS Displacement (RS Tag) for the same object. Not that you mentioned that, but just in case.
All the best
