As you can tell, the 2 cameras have different megapixel count and different sensor sizing. The E-M10 III with its bigger sensor is going to make achieving shallower depth of field simpler and the Olympus E-M10 III will provide extra detail with its extra 6 Megapixels. Higher resolution can also make it easier to crop shots a bit more aggressively. The more recent E-M10 III should have an advantage when it comes to sensor innovation.
