Well, with those tiny pictures I have a hard time telling, but I certainly wouldn't buy those as Enchi's.
Color notwithstanding, they have no Enchi patterning at all. I don't know where you got your Enchi breeder from, but it must be a really poor example of the morph to produce offspring like those. But that is neither here nor there.
I can state conclusively, lots of morphs as well as normals have a mustache. I have a spider with one, a fire with one, a vanilla with one, and two normals who have them.
