Are you sure the keys are burned in during manufacturing? When you remote wipe an iPhone, it wipes the key and the contents become inaccessible. If the key itself is hard coded in hardware, that's not exactly possible to do directly.
And if they were hardware keys, Apple could extract those. They can't. See Apple's iOS Security Guide page 15 for reference.
