In not sure if English is your first language op but undebased is essentially the reversal or opposite of debased. Debased doesn't quite translate to the opposite of immaculate. To debase something means to cheapen it or if a person was debased they would cheap or crass. Undebased therefore doesn't really work as a domain in my opinion as undebased works on the presumption something was debased in the first place and I can't see brands wanting to associate with that personally
