Typically, its tough to visualize the difference between sensor dimensions merely by checking technical specs. The picture below should give you a far better sense of the sensor sizing in the E-M5 III and E85.

As you have seen, both of those cameras feature different resolutions and different sensor dimensions. The E-M5 III featuring a larger sensor is going to make getting shallower DOF simpler and the Olympus E-M5 III will give greater detail having its extra 8MP. Greater resolution will also enable you to crop images way more aggressively. The newer E-M5 III provides an edge in sensor innovation.
