Did I get scammed :(

I went to a LCS trade night and I saw this legendary treasures mew out of someone’s binder. At the time I didn’t realize it was supposed to have sparkles on the holo foil and looking at TCGPlayer it didn’t show sparkle so I okayed a deal with him. I literally stumbled upon a video of someone on tt and it had all the sparkles and now I’m confused. Did I just get scammed?
