How are others displays?
I am noticing some slight blue fringing in areas that display white, the fringing is occurring slightly above, it's not everywhere though. Can be spotted on mine in the News section just above certain coloured news boxes. Comparing my V2, I am not seeing the same issue. Vivid mode is off on my OLED model.
Edit: This is strange, maybe it is my eyes. As closing one eye (tried both) removes the issue. I also cannot capture it on camera. So doesn't seem to be a panel defect. Bizarre.
Just read that the OLED panel seems to use PWM to control brightness. I'm not saying this is the issue, I'm not normally sensitive to PWM and I wouldn't expect this behaviour.
