I'm not a fan of mutations, but each to their own.
I am a bit suspicious about the creams.......they have red beaks which would inidicate Red-billed (Hecks) Longtail blood.......I know you guys overseas dont get alot of new blood and somtimes have to make do with what you have, even if it is hybriising two closely related species. Its also a pretty common method used by mutant breeders

to introduce a desired colour into another species, eg, cream longtail crossed with Black throat to get cream in the blackthroat population.........I'm thinking thats how we got what we see in the photo
