I just looked at what I think is your refurb at Refurbished Mac - Apple Certified - Apple Store (U.S.) and saw this, i.e. that the pic on the screen is Yosemite.
How would anyone know who isn't running Yosemite that the image is not just some wallpaper pic of a mountain? All it says on the refurb page I bought it from is all the system goodies you get, not the OS.
