I would also like to@know if this is the original scent.

Unfortunately, it has been reformulated many times. I own the black bottle of Armani Si Intense from 2014 ( very close to the original scent but more for the winter season) which has been discontinued, and I’ve been looking for a replacement for years. This scent is quite similar to the black bottle once it settles on the skin, though it’s lighter (the black bottle is more syrupy and sweet). Still, the scent is close enough that I’m keeping this as my summer fragrance and Si Intense for the winter.
