In many cases, it can be hard to see the contrast in sensor measurements purely by seeing a spec sheet. The graphic underneath might give you a far better sense of the sensor sizes in the K-01 and A9 II.

As you can see, both of the cameras have different resolutions and different sensor measurements. The K-01 due to its smaller sensor will make achieving shallow DOF more difficult and the Sony A9 II will produce more detail as a result of its extra 8MP. Higher resolution will also help you crop photographs a bit more aggressively. The older K-01 will be behind when it comes to sensor innovation.
