That video was so obviously not LK-99 I doubt anyone sane was fooled by it (anybody who has played with magnets knows that’s how ferrous metal hangs off of them).
We’ve seen proper levitation of specks that hasn’t been falsified yet.
That said, I believe theory has shown it’s actually possible for a diamagnetic object to fully levitate over a magnet as long as it’s light enough, but unlike a flux-pinned superconductor, it will only levitate over the center of the magnet, as is happening in all the levitation videos.
