If the manufacturer is ill-intentioned, of course the switch will be in essence fake.
A well intentioned manufacturer can make the switch working and safe. For such implementation, there won't be "OS flag" about the microphone being on or off, because to protect against privacy bypass by hackers, the OS can't interfere with the switch. The OS can only read the camera and microphone muted output, and guess the switch is probably turned off. The switch is also inaccessible from the usual TV remote, for maximum protection.
Those who don't care privacy will keep the switch always on, while those who care will keep the switch always off. Everyone can be happy.
You can't recover anything if the muted output is electronically come from a different set of signal lines.
