Nintendo’s 1st party labels stopped getting plastic-coated in 1995. First title I bought at launch like that was Killer Instinct and I was preordering all major Nintendo/Rare releases back then. They are decidedly less glossy and get damaged easily, especially across the top edge.
My current copy DEFINITELY doesn’t have a repro label:

That small box isn’t a repro either: It’s an original production display box made with Nintendo's mid-‘90s non-digital publishing techniques. They zeroed out half the UPC to keep retailers from accidentally selling you the empty display box.
My original box/game were stolen from me in the late ‘90s but this crappy label is definitely legit. One way to identify a fake Earthbound is when the label is TOO glossy. Yours looks legit to me... and really nice.
