This is not a correctable error situation under the definition in the NFHS rulebook.
The difference that it makes is that you would have to get the officials to acknowledge their error before the ball was put into play. In a correctable error situation the statute of limitations is the "first dead ball after the clock has properly started."
Of course, we all know that you should report a throw-in plane violation to the table. Although generally they have no idea what to do when you report it
