Oil condition sensor

Or, maybe the "condition" it measures is "present" (read: good) or "absent" (read: not so good).

I've read on the various Bosch and other automotive OEM's about oil sensors that can distinguish condition, but they seemed pretty "prototype-ish". Wouldn't they have problems giving a valid report if the owner put a different oil in the crankcase, or if Castrol reformulated TWS for that matter?
Here is a descriiption from BMW.
