Quite often, it's tough to imagine the gap in sensor sizing just by viewing technical specs. The photograph below should offer you a greater sense of the sensor sizes in the E-M5 III and RS1500.

As you can tell, the 2 cameras posses different resolutions and different sensor sizing. The E-M5 III using its larger sensor is going to make achieving shallow depth of field simpler and the Olympus E-M5 III will provide you with extra detail having an extra 6MP. Greater resolution can also help you crop images somewhat more aggressively. The more recent E-M5 III should have a benefit with regard to sensor tech.
