Yeah. People have been hoping for a signed "Photoshop-proof camera" since digital image manipulation was invented, but it has the same limitations as any form of DRM. It only slows people down a bit. There's also the analog hole - i.e. just stick your "attested" microphone in front of a speaker

Canon tried to do this with their ODD system, and they got kinda close, but it is possible to extract the key from a given camera, and forge signatures.

Their verification system also seems to include a smartcard or SD card-like thing (which might be doing something special, or might just be DRM)

or rip out the wires and attach whatever speaker you want, not really detectable

It is detectable if the other components are cryptographically paired, like they are in newer iPhones.

Go try to swap a camera or screen between two identical iPhone models, it won't work.
