Variegated Frydek

Hello, I recently bought a smallish guy for $30 (had to drive an hour to source one) but I didn’t notice that the newest leaf was all green. The eldest is a half moon, next is beautifully dappled (similar to a syngonium mojito) all across, then green.

While I’m an old hand with alocasias on a whole, I don’t buy variegated anything else as they aren’t my jam. Does this mean it’s permanently reverted or is there a chance it will throw more leaves with white?

Thanks!
