However HDR worth it at any size, but does seem to be limited to 4k sets.

It's subjective, not cast in stone. I tend to agree with you, but many will argue 55" at least is worth it. Hence all the 55" 4K sets. Eventually probably all sets will move to 4K, just because. But right now, as you say, since HDR is linked to quality 4K sets, which generally means 55"+, UHD is not cheap (the point of the original comment).
