Yes is very interesting, actually is my opinion about the almost dragon archetype used in the industry of games and movies. I have the both kinds in my gallery XD. But in a personal range of opinion, I really like to make that difference between wyverns and wyrms.

For example I have a story (which end do someday), where important part of the script is the evolutionary relationship between the two anatomies, the wyverms are in their potentially beasts most fellow human rider, and wyrms creatures of intellect and power magic very than any human. Thanks a lot to comment all this are interesting topics : )
