I have both a Roku Premiere and a Streaming Stick+. I am running this through a Denon 7200WA into the input 2 of the tv. I looked and the Denon says it can do 2160P 60hz. Was wondering if this was an 8 bit, 10 bit thing? I also have a 4k Amazon Fire Dongle, but I don't see the detailed options that the Roku offers.
With my 75Z9D TV the 2019 Roku selected 4K HDR 60HZ, but then later on (couple of hours later maybe) the TV complained that it was receiving a signal that it couldn't display. I power cycled the Roku and manually set it to 4K HDR 30Hz and so far (fingers crossed) it have behaved.
With my X940E TV it's 2019 Roku selected 4K HDR 30Hz.
