Sabre in Blue Dream, looking for more info

I just bought a Sabre in Blue Dream (wow!), which I keep seeing listed as a “special edition” color. In some places it is listed as being from the BFR line but can find no photo of it in EBMM BFR photo galleries. I was hoping to learn the specifics and clarify a few things, such as how limited an edition? Is there a story behind it? Is it a BFR offering? And any other information about the instrument that an owner might want to know. Thanks!
