I have what I believe is a Dolby Atmos compatible TV, Streaming device, and sound bar. This Vizio sound bar gives me a green LED when it detects Dolby Atmos content. This works as advertised. However, I can not detect any thing in the audio that I would expect from Dolby Atmos. Such as object placement in the overhead sound stream. Am I expecting more than is available, or is my setup not giving me true Dolby Atmos sound?
