Are you measuring that while on the Roku home screen? That screen is only 1080, perhaps it's resolution matching. Try it with a known 4K video playing. I admit that I've never heard of a Roku doing resolution matching like my Shield does, but maybe it's something they've added and didn't tell us.

Assuming you have the latest firmware (9.4.1-4212) and have tried different HDMI ports/port settings on your TV, I'd recommend reporting this directly to Roku:

Chat or email:  https://support.roku.com/contactus   (choose setup/ultra/other/need more help?)

and/or message @RokuDanny-R
