The first issue is why only SPDIF is shown (if you see my 2 audio screenshots above), and grayed-out w/no other options. Should be HDMI audio as obviously can't get HD audio with SPDIF. Maybe resolving this will allow HD audio and 3D to play.

Same on all OpenELEC AMLogic devices, HDMI/SPDIF Audio is output via the same ALSA sink. There is nothing to be resolved.
Also these so called TLBB Wizard opening screens are nothing but re-titled bog standard OpenELEC startup screens, nothing special.
I'm seeing nothing but a re-skinned Kodi, using a bog standard OpenELEC image on a S812.
The OpenELEC code is freely available and so are the Skins.

151 Euros for this device is some sort of sick joke if it does not come with a customised Linux Kernel to allow HD audio or 3D. This is no trivial coding matter.
I would expect a TV Tuner to be incorporated into a box at this price too.
You are more likely to see HD Audio passthrough on the new AMLogic S905 before this device even gets out of the starting blocks !
