Dolby Atmos SPDIF with MIBox

[NaorG]

I have MiBOX 4 (with Dolby Atmos support).

I want to buy home surround speakers for the living room and i saw the Samsung HT-J5100K/XL(LINK) (with Dolby Atmos).
in the Samsung website under spec>Connectivity it dos not show SPDIF connector.

on  unboxing video(LINK) in YouTube you can see a SPDIF connector.

 

So, to the questions.

1) Can i connect the seekers to the  MiBOX via SPDIF and have Dolby Atmos sound?

 

2) Dos Netflix support Dolby Atmos?

3) Also what is "audio in" and "HDMI out"?

call samsung about the spdif port. 

only some netfliz shows have DA support

audio in (on the soundbar) means where you connect the source to (source sends "audio in" to the soundbar). 

hdmi out i think is supposed to allow hdmi passthrough by the hdmi in port (plug eg:xbox into soundbar, hdmi from soundbar to tv to allow audio and video of xbox to tv). However, I have not got this to work on my LG soundbar with the MiBox S
