Generally, its hard to visualise the gap in sensor dimensions only by going through a spec sheet. The pic here should provide you a far better sense of the sensor sizing in the E-M1 III and S2100.

As you can see, both of the cameras have got different megapixel count and different sensor dimensions. The E-M1 III featuring a larger sensor will make shooting shallower depth of field less difficult and the Olympus E-M1 III will produce more detail due to its extra 8 Megapixels. Greater resolution will also enable you to crop photos much more aggressively. The younger E-M1 III is going to have a benefit when it comes to sensor technology.
