This doesn't convey any property rights to the art's copyright, unless the purchase also included those separately from the NFT, which, of course, happens all of the time without the NFT silliness and doesn't require NFTs at all.
Buying an NFT isn't like buying a piece of art you can put on your wall, it's like buying a signed, numbered, limited edition card that has the address of where the actual owner has the art on his wall.
...except the address might be wrong. Or become wrong when the actual art changes hands, or the owner dies. Also nothing stops the artist from making a new print run of the cards. Or someone who isn't the artist making a print run of the cards.
But I mean, even if Beeple sells another thousand NFTs referencing the same artwork, and even if this NFT quickly ends up with a broken URL, and even if the buyer of the NFT didn't end up with any ownership rights to the artwork itself...
...at least they can feel pleased they bought the first NFT issued by Beeple with this particular URL on it. That's gotta be worth something! (...$69 million, apparently...)
This is more or less you saying you paid for a receipt showing you paid to have a hash of the same MP3 everyone else is listening to.
This is why you see people making the comparison to sports trading cards. You're not buying the person, you're buying the piece of cardboard.
They can display the receipt but have no more right to the art than you or me.

So no rights apart from the property rights (Christies T&Cs)
So presumably an image file and the NFT. Bit vague on copyright.
