EM-5 Low ISO, there is a RAW difference

There is a RAW difference between ISO 200 and low ISO on the E-M5. At least according to this website http://www.guillermoluijk.com/article/em5isolow/  According to his measurement the RAW file is at ISO 160 whatever that means both theoretically and practically. I would expect a tiny bit cleaner black and the same headroom as ISO 200 if you "underexpose" by 2/3 f/stop.
