Is this a new rokuTV model produced in the last month by TCL or another vendor? I have heard of a few that support both DolbyVision and Atmos. In that case, yes, that rokuTV should show support for atmos in the device.getAudioDecodeInfo
Now for the problem anyone have that TV care to disclose their audiodecodeinfo here? You can see it when using the Blue Neon Night app. In the app, navigate to the Options and QuickViews row. Scroll to the right until you see a big question mark with a circle around it. Under it says "Device Info". Click that and scroll to the bottom. Notice where it says the [Audio Decode Info] bits? Is there some way you can take a screen shot of that with a camera or similar? Seeing that will expose what that model is capable of. Near the top of the device info is about your specific device. Note the model, modelNumber, and VendorName those may help identify it.
If you still think Atmos should direct play do a test. In blue neon, on the detail screen choose "more..." and choose "force direct". Now play the video and see if you hear anything. Or is it, the sound.. of silence?

All of the above are known as ndka. Native Development Kit apps. They can write their own drivers, their own codec engines, their own players. They have access to the linux core of the device at the lowest level.

Here is emby and the emby beta. Using the roku scene graph apps. These cannot extend what the roku lets you do. You have to pay roku, several tens of thousands of dollars and sign large NDA agreements filled with clauses that cause huge lawsuits against you to get NDK access. So at that level, you pay to play. In this case, emby isn't paying to play that game. Using dollars must make sense, or lose both dollars and cents.
