I would say both situations are correctable. You have to correct it before the first dead ball becomes live after the clock properly starts. So if the ball is merely at the disposal of the inbounder, the clock has not started; therefore, it's still correctable.

If the ball is inbounded and kicked, the ball is dead immediately due to the kick. My interpretation would be that the clock should not have started. (So even if the clock operator started and stopped the clock, it wasn't properly started.)

So go ahead and correct the error in both situations.
