Leica M Typ 240 has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor . On the other hand, Nikon Z9 has a
46.0MP Full frame (35.9 x 23.9 mm ) sized Stacked CMOS sensor and features Expeed 7 processor.
Nikon Z9's sensor provides 22MP more than Leica M Typ 240's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the M Typ 240 and Z9 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica M Typ 240 and Nikon Z9 Cameras
Leica M Typ 240 and Nikon Z9 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.
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. Leica M Typ 240 and Nikon Z9 sensors have been tested by DxO and the results show that Z9 has a better overall score of 98, 14 points higher compared to M Typ 240's score of 84.

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 M Typ 240
or the
Nikon Z9 ,
including hyperfocal distance.
