I found the reason for my "Screensaver not working" problem. It's the Bluetooth "Standby" function. I had this enabled previously and everything worked, remote went into standby after a while and screensaver worked as by default. I did remove the BT remote a few days ago since I needed it for a different RPi and then paired it again with the RPi3 running LibreELEC Testbuilds. Enabling Standby for this remote actually prevents it from going into standby and the screensaver from working. Leaving standby disabled and the remote goes into standby and the screensaver works normal.

One related question: I now have a blank device in the BT menu. I tried to connect to it and it seems to be my Chromecast v2. Chromecast doesn't have BT as far as I know though...
