Personally I have been very underwelmed with dolby vision. I have watched various DV shows via netflix on my E6 OLED and at some point I though I had issues with by panel when it turned out dolby vision was the cause.
The main issue I have seen with content using it is line bleed in the source material. Those of you who owned Plasma in the past will know what line bleed is I suspect. Well dolby vision is so great that their cameras or encoding method ends up putting that effect into the source material for you. Its really dire in some of the daredevil series I watched in the past.
I steer well clear of Dolby Vision these days and I would be the first to sign a petition for TV makers to drop DV and bring back 3D.
[EDIT], here is a video clip of a prime example of DV crappyness I recorded a few months back. Its not even a great quality video but you can see the linebleed over the black bricks and his chest as he gets out of bed.
