There are three things that come to mind that might make the Z8/Z9 produce sharper pictures than the D850.
1. IBIS
2. Better autofocus, though the autofocus of the D850 is outstanding. It just doesn't match what the Z8/9 can do.
3. Better lenses. Most of the Z lenses test better than their F mount counterparts, though not all, and some third party lenses match the Z lenses pretty well.
This could all be true. But I have spent all the Nikon dollars that I'm likely to spend for the next several years! And by then, I will likely be dead!
