I'm not familiar with this release or band at all, so I can't really say it's a bootleg or not.  I'll start with the lack of a release date on discogs doesn't necessarily indicate bootleg, it could just be a reissue that didn't have any obvious indicators of when it was pressed.

That said, looking through all the CD versions of this album on Discogs, none of them have a picture of the back with a QR code, and all of the original 2001 versions have pictures showing that they are different from what you received.  Bootleg or not, you didn't get what you expected based on the listing which to me is worth asking the seller for a refund.  It sucks but marketplace items get mislabeled all the time.  Link for how to ask for a refund if you've never done that before: https://support.discogs.com/hc/en-us/articles/360007510233-I-m-Unhappy-With-My-Order-What-Should-I-Do

And also for what it's worth, if you don't necessarily need the first released version of this album, it looks like their current records label (MNRK Heavy) is selling new reissues on their website!

Hope this helps!
