I'm having some problem here, as I can't see this wrong "gamma". Can you please elaborate on it?
If you are talking about the bars with a grey colour not so solid (well, sometimes going pinky), then this is definitively due to theora compression. You're using a lossy codec, and this is its normal behaviour. Other artifacts you can see in your video are obviously related to it too. So I think this isn't bug in istanbul, but how compression works. Next version of istanbul will probably come with a more flexible compression/quality chooser, which will help here.
