Normally, it is very hard to visualize the gap in sensor sizing simply by seeing specifications. The photograph underneath should give you a better sense of the sensor sizing in the E-PM1 and K-1.

To sum up, both of those cameras offer different resolutions and different sensor sizing. The E-PM1 featuring a smaller sensor is going to make achieving shallower depth of field trickier and the Pentax K-1 will show more detail as a result of its extra 24 Megapixels. Higher resolution can also enable you to crop photographs a little more aggressively. The older E-PM1 will be behind with regard to sensor innovation.
