Plainly, both cameras posses different resolutions and different sensor sizes. The K-01 because of its larger sensor is going to make getting shallower depth of field less difficult and the Sony RX100 IV will show more detail due to its extra 4 Megapixels. Greater resolution will allow you to crop photos somewhat more aggressively. The more aged K-01 will be behind in sensor tech.
