Capable receivers matter not if device used for streaming is limited by hardware or is not supported by service. When choosing a service, one needs to check for devices that support everything that service has to offer or deal with limitations from devices not in the service eco system. Even then, issues arise. TV's aren't the best place to look for apps that support services to their full potential. You may get two good apps to go with the rest of the crappy ones. Say, doesn't Marantz' HEOS app support 24/192 from Amazon Music Ultra HD? Try using it instead of the TV app.
