Typically, it can be tough to visualise the gap between sensor measurements purely by reading through specs. The graphic below will give you a clearer sense of the sensor dimensions in the E-M10 III and VS20.

As you can plainly see, the two cameras have the same megapixels but not the same sensor measurements. The E-M10 III contains the larger sensor which should make achieving shallower depth of field easier. The more modern E-M10 III is going to have a benefit when it comes to sensor technology.
