I was not giving an exhaustive list of formats, only pointing out the fact that "high definition" is not one format, but more than one, that are significantly higher resolution than "standard definition," which is also more than one format. And now there is "ultra high definition," which also is more than one format. If one wishes to be specific, then one must say something more than "standard definition," "high definition," or "ultra high definition," as each of these expressions refers to a range of different formats.
