Sometimes, it's hard to envision the gap between sensor measurements merely by going over specifications. The photograph below might give you a stronger sense of the sensor dimensions in the E-M1 III and WG-1.

Plainly, both of these cameras have got different resolutions and different sensor measurements. The E-M1 III with its bigger sensor will make achieving shallow DOF less difficult and the Olympus E-M1 III will offer you extra detail with its extra 6 Megapixels. Higher resolution will make it easier to crop photographs much more aggressively. The more recent E-M1 III is going to have an edge in sensor innovation.
