Neither are hypos, as you can see by their claws. Hypos will have all clear claws while het hypos or just regular dragons will have dark claws. However they could be het for hypo.
The first video the dragon could definitely be het for trans.
Really no way to tell if a dragon is het for a gene unless you know the parents and their genes or you've proven the dragon out.
As far as the colors go I definitely agree. Although I'm not too good with my bearded dragon color phases, at least the red color phases. Yellow and orange color phases i'm decent with.
I know a very good beardie breeder who has great beardies with spectacular colors and great health with good genetics. Here's a link to her website: http://www.dachiubeardeddragons.com/
I believe that Carolina classic dragons specializes in those types of beardies that you are looking for. I Have heard that Carolina classics is also very reputable.
I Have heard that Carolina classic dragons, Blood bank dragons, and Dragon spots were also reputable breeders. But Dachiu bearded dragons is my favorite. I've never bought from her before, but I know she's a very reputable breeder.
