Both Nikon D4s and Nikon D4 have Full frame sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the D4s and D4 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D4s and Nikon D4 Cameras
Nikon D4s and Nikon D4 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.

At Camera Decision, we also look at Dxo Mark sensors when available as we think it is a good indicator of image quality.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Nikon D4s
or the
Nikon D4 ,
including hyperfocal distance.
