I have purchased an ungraded home theater system that includes a Sony 77-inch OLED TV and a Denon AVR X4500H receiver. Installation is presently delayed owing to the quarantine, but is expected to take place late next week. I have a Bolt, purchased in August 2018. I'm wondering if the Bolt is going to stream 4K programming from Netflix and Amazon Prime, which are presently the only streaming services I use. The dealer who put the home theater package together for me isn't familiar with the TiVo. She says she usually installs a Roku Ultra in systems like mine when streaming capability is desired. I can purchase a Roku Ultra, but I would rather just have the Bolt serve this purpose if its up to it. There have been a few message threads on this topic (yes, I did search before I posted this), but they're mostly 2-3 years old. What I was able to suss out from the previous discussions is that the Bolt streams the 4K signal well enough, but may not be able to deliver on HDR. Can anyone tell me whether the Bolt can/will deliver all the functionality of the Roku Ultra, or should I just buy the Roku and be sure to get the full performance?
