That is accurate. I remember watching this channel in upscaled version, and then they replaced it with 1080i 16:9 ratio. It is in fact a HD channel. If it was an upscaled one, I'd be able to tell the difference.
That's bcoz Nat Geo Music SD channel had shut down and now all operators use downscaled HD feed of Nat Geo Music HD. Just 16:9 aspect ratio does not make a channel HD
