This is the email I received from Onkyo regarding the loss of Dolby Vision when attempting to pass through an Onkyo receiver after the last ATV4K update.
I’ve just tried with our TX-NR787 and AppleTV 4K, I was able to pass Dolby Vision through to the TV. What brand of TV do you have? We have noticed that some TV manufacturers will enable only the base level Dolby Vision pass-through which can lead to output issues.
Have you made sure the TV, receiver and AppleTV are all up to date with their software?

Is anyone currently able to repeat this with their equipment?
