Hi Maybe it will not work for all, but I found a solution for turning on my Apple TV with my Sofabaton X1 remote. The way it worked for me was to go the the Activity I wanted the Apple TV to be turned on by, and go to <Edit> in the top right corner, then go to <Startup settings> and in there press <Add a command> The command I added is set as follows: Device = Apple TV and Commands = Homepage The homepage button on the original Apple TV remote can be used to turning on the Apple TV box. For turning off the Apple TV I did not do anything, it seemed to work the whole time, I am not sure why, but could it be controlled via the Denon Receiver via the HDMI? I have no idea. My Apple TV is a 3rd gen with 128 GB HDD. I hope this helps.
