On my Roku 4, I have no such issue, but it's not connected to a 4K set.
I just sent back my Roku Ultra yesterday. I got it over black friday and had problems using it when connected directly to my Samsung 65" KS8000 4K HDR TV as well as my Onkyo 646.
At first, I connected straight to the Samsung TV but whenever I tried to watch 4k HDR content, I would get an HDCP error. I'd then have to just escape out of the Roku app by hitting the home button. I did discover that if I disconnected the HDMI cord after seeing the hdcp error and plugged it back in, the content would play. But of course that's not practical.
So then I tried then to connect the Roku Ultra directly to my Onkyo 646 receiver in the STB port and the HDCP error was gone. I already didn't like this because I was losing out on the Samsung TV "1 remote to control everything" feature. It was nice not to have to switch remotes and also not have to switch within the receiver between the various devices. That's how I used to watch in the old days with my older Onkyo - all my devices went straight to the receiver, and then receiver went to the TV.
But then this gave me another weird problem where if I started watching something, my receiver would play the video and sound, and then go out of "STB mode" into "TV" mode and then I'd have to click on the "STB" button again on the receiver to get the roku content again to start playing.
So now my Roku Ulta's returned. I don't really need it right now anyways. All the 4K HDR Content I want is available from the Samsung Smart TV apps anyways - especially now that Samsung's YouTube app plays HDR as of this week. I went back to my Roku 3 for now. Hopefully Roku resolves this problem by the time I need to buy the Roku Ultra again when it has more 4K HDR content that Samsung's Smart Apps don't have.
