Both Nikon Z6 and Nikon Z6 II have Full frame sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the Z6 and Z6 Mark II sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon Z6 and Nikon Z6 II Cameras
Nikon Z6 and Nikon Z6 II 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.
DxOMark Sensor Scores
Both Nikon Z6 and Nikon Z6 II sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, Z6 has scored 95, 1 points higher than Z6 Mark II.

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 Z6
or the
Nikon Z6 II ,
including hyperfocal distance.
