Dale is suggesting you examine the surface using a jeweler's loupe. Myself, I am with Chuck and think that, at most, someone may have tried to hand-buff a shine on it. But I think the surface looks original from the views you show.
Huh, Thanks Chuck, I don't recall discussing this type with either Ron or Bill for many years. They must've gotten together on a rename and I must not have been paying attention.
My guess is that this marble is not veneered. If that is true, I'd say it's just a nice patch - no particular type that I can think of. If it is veneered, I am with Art - some sort of a Conqueror variant.
They are Alleys and they are "flamey" but I am not sure I would call them all "Flames". These days, I think most folks like to see 5 "stacked" flame tips for the "Flame" designation.
