Typically, it is hard to visualise the contrast in sensor sizes just by checking out a spec sheet. The picture below might give you a far better sense of the sensor dimensions in the E-M10 IV and a5000.

Clearly, both of the cameras provide the same megapixels but not the same sensor sizes. The E-M10 IV features the smaller sensor which is going to make achieving shallower DOF trickier. The newer E-M10 IV will have a benefit with regard to sensor innovation.
