Is the signal on a beamer better if you connect the Swisscom Box or Android Box to the receiver?

HDR does not work for me with the Xbox One via the receiver. HDMI settings are set to "ENHANCED", high-quality cable - but the receiver does not loop through HDR. HDR does not work with Apple TV 4K either. I connected the Xbox directly to the monitor (LG 38WK95C-W) and connected the audio to the receiver via an optical cable. The monitor then also shows when it receives HDR signals.
