Is this a (really good) fake? 42141

So I have been a long time Lego collector I bought this secondhand supposedly it was new and sealed. You can tell the tape was opened at one point and put back on, but it is the legitimate Lego tape. It looks like. I don’t know what it is about this but something just looks off to me about these bricks. I tried my best to take some up close pictures of them as well as the box. Does anybody have any insight? I can’t exactly say what it is. I think the box is real but the bricks just give off...
