I can see what you mean. Yeah, this tool is more useful for a technician who is looking to confirm a suspected infection. It can give you a clue to if you need to mitigate a possible leak.

But of course if you suspect infection you should thoroughly wipe your device.

Just as a side note if anyone is reading this because they are thinking they need to wipe their device, not all ways of wiping are created equal. Make sure you are fully wiping your device, not just clearing the settings.

Unfortunately most information for good security practices comes from national intelligence agencies, and GCHQ in Britain has published good information regarding secure wiping of devices that are suspected to be infected, for iOS specifically you need to use DFU mode to restore the device to a fully clean state.

More guidance is on the GCHQ site: https://www.ncsc.gov.uk/collection/device-security-guidance/managing-deployed-devices/erasing-devices
