Often, it is difficult to visualise the gap in sensor sizes only by going through technical specs. The picture here may provide you a more clear sense of the sensor sizing in the GX7 and K-3 II.

As you have seen, each of the cameras posses different megapixel count and different sensor sizes. The GX7 featuring a smaller sensor will make shooting shallow DOF harder and the Pentax K-3 II will produce extra detail due to its extra 8MP. Greater resolution will also make it easier to crop images somewhat more aggressively. The more aged GX7 will be behind when it comes to sensor tech.
