A chain of hardware, all with private keys in a 'secure enclave' / 'TPM' can deliver DRM that is as unbreakable as the private keys are hidden and tampering detection is functioning. Really, the only hole that can't be patched is analogue recording. Realistically, tampering with the screen or cable is probably the easiest target. Though, compromising the TPM would have more widespread effects.
