Yes, if the X1 box is set to output 2160p, the X1 box is upconverting 1080p (or 480i, or 720p, or whatever resolution it is receiving, other than 2160p) to 2160p. So when you ask the TV about what resolution it is receiving, it is receiving 2160p from that HDMI port, so the TV just shows you 2160p when you hit the "Info" button (or whatever it is called for your TV).
I am still on an iGuide DVR so I don't have access to the Netflix app on the X1 box. But the first-generation Roku I have and the Netflix App on my "Smart TV" have the ability to report the resolution of the stream it is receiving from Netflix. So you might check if the Netflix App on your X1 box will display information for the stream it is receiving. (My notes, which predate UltraHD, indicate possible streaming resolutions for Netflix are 240, 288, 384, 480, 720, and 1080, and indeed I have seen the Netflix App for my TV report 384, 480, 720, and 1080.)
If the X1 box was able to send to the TV the same resolution it receives (one of the features the iGuide boxes, at least the DVR I have, that the X1 DVR lacks), one would likely notice almost a second of no picture when the resolution being received on the HDMI port changes, such as switching the cable box between channels of different resolutions. I would imagine this would be much worse for streaming a video since the streams Netflix use are adaptive streams, changing resolutions when Netflix-to-App throughput changes, and when streams require a higher bit rate for fast changing scenes, so when an action scene comes up and the Netflix stream downgrades from 1080 to 720 the second of blackout while the TV detects the new resolution would utterly destroy the action scene. (I'm speaking about changing bit rates required from action scenes from experience: I have watched some action movies with the Netflix App displaying the instantaneous resolution on the screen, and often it is 1080 for mostly static scenes like dialog and steps down to 720 for an action scene, and back up to 1080 for closing credits.)
Anyway, the TV reporting the resolution on the HDMI port is just what also happens when I play a DVD (480i) on my Blu-ray player: the TV reports 1080p because that is what the Blu-ray player is sending out its HDMI port.
