Paramount+ 4k Content on 4k Box?

Paramount+ has mostly 4k content now, but on Xfinity the app does not support 4k content.

Is there any information on when the Xfinity 4k Boxes will support 4k on Xfinity Paramount + App? 

Thanks. 

Is Paramount+ in 4K?

No, currently the Paramount+ app on X1, Xumo Stream Box, and Flex doesn't have 4K content
