Sony A7R IV has a
61.0MP Full frame (35.8 x 23.8 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Leica SL3-P has a
60.0MP Full frame (35.8 x 23.9 mm ) sized BSI-CMOS sensor and features Maestro IV processor.
Another similarity between these two cameras is that both Leica SL3-P 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 SL3-P sensor size comparison.

Sony A7R IV and Leica SL3-P have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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
Leica SL3-P ,
including hyperfocal distance.
