Both Sony A7R IV and Sony A7R V have Full frame sized 61.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another similarity between these two cameras is that both Sony A7R V and Sony A7R IV sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the A7R IV and A7R V sensor size comparison.

Sony A7R IV and Sony A7R V 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Sony A7R IV and Sony A7R V sensors have been tested by DxO and the results show that A7R V has a better overall score of 100, 1 points higher compared to A7R IV's score of 99.

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
Sony A7R IV
or the
Sony A7R V ,
including hyperfocal distance.
