Blueberry x Haze/Blue Dream?

Yo everyone. I was just wondering what the difference between blueberry x haze and blue dream is? From what I can find they are either closely related through different haze crosses or they are exactly the same. Any thoughts?

Real Blue Dream is clone only from Santa Cruz. It's a cross between this local haze this guy had been working on for about 7 years when introduced DJ Short's Blueberry into the genetics. He sprung up one random pheno in a large outdoor crop. Any Blue Dream from seed is a Haze/BB attempt at a copy.
