I assume you mean when watching the Apple TV app on the EETV Box Pro?
As far as I know the box will always output DD+ when in surround mode, in normal Stereo mode it will be just that. My Amp will always show DD+ on it regardless of what im watching on the box itself, are you connecting directly to a TV or using a AVR or soundbar etc?
Can you watch HDR content on Netflix or do you have access to the TNT Sport Ultimate HDR channel which just runs a loop all the time, I dont think you need to be subscribed to view that, but it will test if HDR is working. (Channel 465)
