That's where DRM comes in. The content is crypted so that only your firmware which has the correct keys can decrypt it. Firmware will do that only if boot was secured. "Content" can be anything; challenge from your internet bank, video stream, code loaded on game startup etc.

Given the way UEFI works, it'd be trivial for you to extract the decryption key in any such scenario.
