Have you installed the latest firmware (4.1.1) as that fixed an issue with the HDMI inputs from computers (and may perhaps be related to this issue).
However I am guessing the issue is very likely an HDCP issue (all Bluray players will definitely set the HDCP flag - and the ATEM will then not display the video).
The Apple TV will flag HDCP if the content being displayed is protected (e.g. Itunes / Netflix).
However if you are just at the menu of the Apple TV that should be passed just fine. You of course have to configure the Apple TV first using an attached monitor to the correct video standard the 4K is setup in.
