dolby atmos via somos arc through ARC?

Have you tried playing Atmos content through your internal TV apps?

I dont have aatmos Soundbar yet, want to know if its worth to get ARC. 

According to this website, your TV supports Dolby Atmos through Dolby Digital Plus. https://www.rtings.com/tv/reviews/sony/a8g-oled

Dolby Digital plus can carry atmos content.  However, only streaming sources are likely to be in DD+, while bluray discs will be in TrueHD, which requires eARC.    As well, just because a TV is ARC capable does not mean it will send atmos content through to the Sonos Arc.   You’ll either need to talk with someone who has the same TV as you, get an answer from Sony, or just test it out yourself.

This chart is generally useful, but not for your question specifically.

The other option is to bypass the restrictions of your TV and get an Arcana, which is available for preorder.

If i understand you correct:

an exemple: Netflix shows in dolby digital plus, which Also my tv is supported. If i put arc througt ARC it should be atmos sound ?

Based on the RTINGS website, your TV should play Dolby Atmos content via Dolby Digital Plus through the internal Netflix app on your TV. Be sure you have a “premium” Netflix subscription so you have access to Ultra HD content with Dolby Atmos audio.

‘should’ is the operative word here.  Also note that most content in Netflix, everywhere really, is not available in Atmos.

I was wondering because its maybe stupid to even think about ARC If my tv is not support atmos sound in any dimension, and i should consider beam.  But if i understand this correct some content should been played in atmos sound and its not Waste to get ARC with my tv?

What is your current setup? What streaming services do you use? Do you use any external devices like an Apple TV, Roku, or Fire TV Stick? Are you planning on using a Blu-ray player? Whether or not you get Dolby Atmos content depends on what your sources are.
