We're talking about a 48MP camera here, so finding a sufficiently "high-resolution monitor" to pull this off is probably more difficult than you expect. Especially because without at least a few times as many pixels as the camera, it's likely that there will be detectable moire patterns in the image. My guess is that a physical print is more fruitful, but it's still a pretty tricky task to get high enough dynamic range and such to truly fool the sensor. This sort of concern is presumably why Apple says "Using a neural network with hidden weights, PCC computes a confidence score for the photograph." I'm assuming that things like moire-patterns from pointing the camera at a screen would be caught by that check. It's of course physically possible to fool the sensor, but at some point it becomes cheaper to just build a UFO and fly it over the actual Golden Gate Bridge.
