In which ways, and why, are smaller sensors more efficient than larger? Part 2

Question about DR for various sensor sizes

Could you briefly explain why dynamic range for smaller sensors is often very close to what it is for larger ones?  For example, IIRC, the E-M1 at most ISOs has DR within 1 EV of D800 (And almost identical at ISO12800).  This goes against the myth that there should be a 2 stop difference between the M43 and FF sensors.  Is this due to pixel size?
