Leica M11-P has a
60.0MP Full frame (36 x 24 mm ) sized BSI-CMOS sensor and features Maestro III processor. On the other hand, Sony A7R V has a
61.0MP Full frame (35.8 x 23.8 mm ) sized BSI-CMOS sensor and features Bionz XR processor.
One other difference between these two cameras that is worth mentioning is that Sony A7R V's sensor doesn't have an anti-alias (Low-Pass) filter. 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 M11-P and A7R V sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M11-P and Sony A7R V Cameras
Leica M11-P and Sony A7R V 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 M11-P
or the
Sony A7R V ,
including hyperfocal distance.
