Roku Ultra 2018... passthrough for Dolby TrueHD / Atmos , DTS-X, DTS-MA, etc?

I'm seeing conflicting info on the web, this forum, etc. Roku Ultra Web Site shows...

DTS Digital Surround™ pass through over HDMI
Dolby Audio™ and Dolby ATMOS® pass through over HDMI


Does it properly pass through lossless DTS-MA and TrueHD?

I stream my own DVD & BluRay rips. Without DTS-MA & TrueHD Atmos working, I won't want a Roku.

Negative. No lossless audio. But the web site is telling the truth, just not in detail. It will passthrough lossy DTS and DD via HDMI to an AVR that can decode it. And the Dolby Atmos it is referring to is the Dolby Digital Plus/Atmos offered by Vudu and a few other online sources. 
.
The only player I know that supports lossless audio bitstreaming for under $200 is the Nvidia Shield. That is precisely the reason I bought one. I still use and enjoy my Roku players and TVs, but for my 4K display I have the Shield to play the audio as expected. This includes TrueHD/Atmos and DTS:X from my UHD Blu Ray rips on my media server.

Dan, thx. I mainly wanted the Roku to use Emby and Amazon Prime Video. If I can't stream TrueHD and DTS-MA, it has far less value to me... Kicking myself for not having bought a Shield on BF.

Is there any Roku device now that will properly passthrough TrueHD and DTS-MA, etc...?
