Your entropy is still reduced, but the number of possible combinations is increased. IOW, you all suffer from the fact the pool of private keys is (MUCH) more limited. But to move funds you'd need the right combination of three of them. (2 xprvs and all three xpubs). You are safer, but if I were in your shoes I'd CAREFULLY move the coins. A Bip 39 passphrase helps quite a bit but is one more way to complicate and therefore shoot self in foot. 😁 whatever you do take care to do it well.
