Here's an update to my own post. The TCL R615 doesn't output Atmos through the TV's Netflix , Prime and Disney+ channels. However it does passthrough Atmos to the Sonos arc through the NVIDIA SHEILD, Netflix and Prime confirms Atmos content on Sonos app except for Disney+ .
Has anybody been able to output Dolby Atmos from these streaming channels NETFLIX, PRIME AND DISNEY in their Atmos capable soundbar from a TCL R6?
FYI. The latest update to Roku OS Version 10 and a subsequent update to the Netflix app now provides ATMOS support on my TCL Roku P-Series TV from 2017. I thought that Netflix would never go back and support my older hardware, so I was pleasantly surprised today after the updates were applied. PRIME VIDEO, DISNEY+ and HBO MAX have supported ATMOS, so I don't know if the Roku OS update changed something or if that was required for the Netflix app to update and support it. Either way, glad it is available!!
