Not really. The blockchain doesn't rely on a central authority. Each entity can publish to the blockchain *and* can read the blockchain. But they can't alter the blockchain or change history as they could in their own database.
Let's say Activision mints tokens for "Call of Duty" skins. Users can trade the tokens, blah, blah, blah, they get the skins in the game. But *anyone* else can read the blockchain.
Take a "Call of Duty" message board, completely unaffiliated with the game. Since users can prove they own a token the message board can use that information for whatever: to allow those users to have a different display or tag or access or run a poll "Who here with Skin X uses it often?" and only people who actually do have Skin X can vote.
Soon "Destiny 4: Gleaming the Cube" is released and people start trading Destiny gear for Call of Duty gear. Two different publishers. One blockchain. Fully capable of interoperability.
This is of course a trivial example. There are so many possibilities for NFTs that it's impossible that there isn't at least one that will take off. I feel like it's the 90s people telling me why email won't be a big deal or the early 2000s that movies are too big to be practical to pirate or stream.
I guess the TLDR would be: Centralized databases can be changed arbitrarily, blockchains can't.
