100% correct. You can use the continuum shortcut or the "connect" tab when you slide down and expand the notifications tab. After that, continuum and old school Miracast (screen mirroring) are possible.I tried it earlier with an older Roku and had no issues at all connecting. You have to ensure that screen sharing is activated on the Roku and WiFi is on. It doesn't take long for the Roku to appear in Continuum.
