“This phone is not unlockable now. It’s just difficult to unlock, but Apple can make it happen, just as they made it happen in 70 other cases.”
That 70 phone case you refer to was before the new iOS 9 system on the iPhones of today.
From what I have read, the IPhone 5C (which is what this is) does not have a hardware secure enclave.
It is likely breakable with a firmware update.
