Both Canon M5 and Canon M100 have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the M5 and M100 sensor size comparison.
Canon M5 and Canon M100 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. Canon M5 and Canon M100 sensors have been tested by DxO and the results show that M100 has a better overall score of 79, 2 points higher compared to M5's score of 77.
