How come we never often see good looking geckos with stunning colors here, just normal looking ones

I noticed that most keepers in the US or other countries have trouble getting their hands on the prettier color/morph of leopard geckos, I just kinda noticed the geckos posted here are the normal/wild types, and that the owners don’t even know the morph let alone the parents of their gecko which is the most important info, also most people here don’t know when their gecko hatched or what the age is even
