Rule of the thumb that hybrids usually do not come thue from seed. Some will resemble parents to certain degree but still will be off type- some characteristics won't be carried. They need to be propagated by division or other means to be completely similar. Your seedlings might not have leaves as dark or colors as bright or height as such etc.
I did have seen seed of Doppelgangher seeds sold commercially which means that some significant % will come true to type and it is reliable seed strain. If you do not see such seed being sold commerically it most likely means it can not be propagated by seed.
