I honestly don't get Dolby and their not implementing 3D technology into their Dolby Cinema theatrical set ups - I think only two theaters have the Dolby Cinema 3D systems --- anyhow here's a nice video touting the Dolby Cinema release:
on a technical note here's the DCP file encode:
6.0 foot lambert version

2K_FF_20160726_DTB_IOP-3D_OV
2K image, 5.1 surround sound mix.
If a UHD edition is to appear when the movie makes it's debut on home video - the image will be uprezzed, and (fingers crossed) Dolby Atmos sound (7.1 core mix).
