IIRC there is about 0.5-0.75 quarts of oil that doesn't get changed as part of the standard oil and filter replacement process.
I check the oil level when the car is warmed up (operating temp) and use the dipstick as the final indicator. I tend to ignore the electronic readout, it seems somewhat variable.
