Watching BluRay 3D via Airplay

iMac 5k 27 Summer 2015, latest update on all software

ATV 3

Panasonic UJ-265 USB 3.0 BD-R

Epson 6600W, ELPGS03 shutter glasses, polarized 3D-glasses as well

Mac Bluray Player unregistered

Hi, I have some trouble getting Bluray 3D experience in the configuration described above. For example, I played Mad Max Fury Road 3D and Shrek 4 3D with Mac Bluray player and streamed it via ATV3 (LAN, not wireless) on the Epson 6600W. The result seemed 2D on the Mac screen, the 6600W reported "No 3D signal".

Would I need another DiscReader instead of the UJ-265, another software to play the discs or anything else?

I tried some 3D clips from youtube via airplay and it worked pretty well with the ATV3, the 6600W and the shutter glasses. The pictures actually left the second dimension and entered the living room. I expected some experience like this when playing the movies mentioned above or any disc that is marked "3D". Am I wrong with these expectations?

Thank you very much in advance for any hint.
