These are all recolours from mounts available via other channels. Then there are all the drake mounts from WotLK and Cata which are just recolours of WOW Classic TBC Gold rare spawn drops/reputation/achievement rewards.
There are other raid mounts which I didn’t mention, such as Glacial Tidestorm from mythic Jaina, which is a reskin of the shaman class mount, or Ny’alotha Allseer from mythic N’Zoth which is simply a reskinned jellyfish mount.
It’s dependent on what you mean when you say “reskin”. It’s dependent on what think you mean by “reskin”.
The only “original at the time” mythic mount I can imagine is Archimonde’s Felsteel Annihilator. The Sylvanas mythic mount is a unique type of mount.
A recolour can be described as a swapping of textures. I’m not sure what the definition of the word means. It’s much simpler than any other task to buy WOW TBC Classic Gold recolour, as they simply have to alter the color using a slider . And call it done.
