I believe it requires an Oscope or similar test equipment. Long term observation of an air/fuel gauge can show a degrading sensor (speed of response on the needle). Basically, once warm, most if not all, read out between 0 and 1 volt. There's nothing to clean, its a pull and replace job. Search for how if you decide to DIY.

are the readings from left and right O2 sensors are nearly the same?
if engine works ok then they are supposed to be the same.. right?

if the two engine banks are perfectly matched, then yes - to the precision of the sensor itself. But if one cylinder is misfiring then no.
