Sure, but keep in mind the prerequisites for using that leaked data. You have to either place yourself in between the sensor and the rest of the device or physically recreate the biometric with enough fidelity to fool the sensor. These are both possible, yes, but they’re significantly less trivial than using a password. This, by the way, still also requires physical access to the device if used for local authentication. And in the event biometrics are used in a physical location (which I’m not personally a fan of, but let’s consider it anyway), there’s often also a human there as well. Your clever mask may fool the sensor, but it probably also still looks like a mask to the guard behind the desk.
