Typically, it can be hard to picture the contrast between sensor sizing purely by reading a spec sheet. The graphic below might provide you a better sense of the sensor measurements in the E-M1 III and T900.

As you can see, both of these cameras come with different megapixel count and different sensor sizing. The E-M1 III because of its bigger sensor is going to make getting shallow depth of field easier and the Olympus E-M1 III will deliver greater detail as a result of its extra 8MP. Higher resolution will also allow you to crop photographs a good deal more aggressively. The more modern E-M1 III should have an advantage when it comes to sensor tech.
