No. It is UHD. But, some of them, at least, aren't 3840x2160. For example one that I'm looking at now is 3840x1600. So there may be more to it than just the encoding parameters.

[Edit] In fact, several of the files I've looked at (that I had previously tested) are actually 3840x1600, which seems to be a fairly common format for reencoded MKV/MP4 files (even though the file title says "2160p"). In the end it may turn out to be the non-compliant sizing that is the real issue. But the original point is still valid. People may think they are watching these in UHD when they are actually simply watching an upscaled representation of it from a picture that was downscaled to 1080p. I know that is true at least on my Sony player, I can't speak for other units.
