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

Leica SL3-P and Sony A7R IV 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
Leica SL3-P
or the
Sony A7R IV ,
including hyperfocal distance.
