Not sure why you want to waste money on a soundbar... but to answer question:
1) No, you won't get any Atmos material from the TV because there are no online streaming sources that currently has Atmos. Even if there is, eARC is needed and at this point in time, it's not clear yet if HDMI 2.0 can be firmware updated to include eARC.
2) Yes you will need an external device and a source material that actually has the Atmos track for the soundbar to decode it.
Buying Atmos for the sake of Atmos is like buying a 4k TV for the sake of 4k. It goes hand in hand.
Thanks for your response. However since my question was unanswered here yesterday and I really needed the answer, I did some readings in regards to my own question and surprisingly it does support Dolby Atmos through HDMI ARC in the form of DD+. LG OLED 2017 can do this over the HDMI ARC, however when doing Atmos through Dolby True HD (via BluRay disc) then it isn’t supported as mentioned by you, it’ll be supported when HDMI Rev2.1 is supported by tv manufacturers via eARC or I can, reroute it via external device via normal HDMI IN on the TV itself. My planned setup is fairly simple as most of my Atmos materials can only output Atmos tracks at 48kHz in the form of DD+, via a PC. The soundbar alone personally is really basic, with one HDMI IN and one HDMI OUT (ARC) and better Atmos soundbars eg; Sony or Yamaha YSP5600 costs absurdly high.
Anyway, I don’t really fancy thousands of ringgit on Atmos HT setup alone and i know a proper setup could cost thousands of ringgit, after some reading on the reviews of the SJ9, maybe a slight taste of Atmos in the form of a soundbar suits my style and budget more.
Took the plunge just now and bought an OLED 55” C7 at RM7999 with the free LG SJ8 soundbar and bought the SJ9 for the sake of experiencing Atmos. Not a proper setup for Atmos but for normal people like me, it might be enough already for now.
