Usually, its difficult to visualize the contrast between sensor sizing merely by going over a spec sheet. The visual here should provide you a clearer sense of the sensor sizing in the E-M1 III and TG-860.

Clearly, both the cameras come with different megapixel count and different sensor sizing. The E-M1 III having a bigger sensor is going to make achieving shallow DOF easier and the Olympus E-M1 III will offer you greater detail using its extra 4 Megapixels. Higher resolution can also help you crop shots a good deal more aggressively. The more modern E-M1 III should have an edge in sensor innovation.
