Quite often, it is very hard to envision the contrast between sensor measurements simply by reading through specifications. The photograph underneath might provide you a more clear sense of the sensor sizes in the E-M5 III and TX66.

To sum up, the 2 cameras have different resolutions and different sensor measurements. The E-M5 III due to its larger sensor will make achieving shallower DOF easier and the Olympus E-M5 III will give you more detail due to its extra 2 Megapixels. Greater resolution will make it easier to crop pics a bit more aggressively. The more modern E-M5 III is going to have an edge in sensor technology.
