Bloom can be disguised, for display purposes only, using a little silicon oil.
It would be absolutely wrong and illegal to disguise it in this way then sell it as perfect, but it would stop it annoying you.
It's also, perhaps, something you should look out for when buying.
The only way to remove it permanently is by grinding it off, using an abrasive and a turning machine. The bloom is part of the surface of the glass.
