No problem with your findings at all (even though, I guess another picture profile or even higher bitrate through HDMI, as for instance, can bring another outcome : )
I just found it funny enough and very accurate definition BTW ;-)
On topic, take a look on this one here:
You'll find the same chroma smearing going on with other cameras, take a look on minute 00:46 of that example above. Saturate the colors just a bit and see the ear of the guy. Same effect. So, everything can be controlled either in the camera settings or at post for sure, the more avoidable the possible, I concur though.
