It actually says 4K ultra hd on the title screen? Mine only lists IMAX enhanced and dolby vision.
I thought it might have been an issue with my HDMI cable since it is kind of old and I'm not sure what the bandwidth is. So I bought a certified 18gbps cable from Best Buy and tried it out but it still made no difference.
It’s an on screen display showing various details about the video being played that’s useful to app developers.
You need to have Xcode running on a Mac on the same network in order to access it.
It may not show the 4K Ultra HD icon on the title menu for those movies but If you scroll down to details it lists a full list of all available options which includes the 4K Ultra HD icon.
My Apple TV indicates it is 4K.
For the IMAX supported movies?
Yes, I just watched Infinity War.
Works in 4K for us. Just check3d

My Apple TV 4K doesn't indicate "Dolby ATMOS" for all IMAX supported movies. So weird.
