bsx_get_magcalibaccuracy and the accuracy from bsx_get_magcalibprofile should be the same. If it is less than 3/3, I would personally not trust this heading too much. Once it reaches 3/3, it should only get out of a calibrated state if there is a magnetic disturbance.
bsx_get_orient_datastatus is a bit different since it takes into account also the gyroscope and accelerometer. This is more likely to be <3, but if you are interested in heading accuracy, the magnetometer accuracy indicator is what you need.

My understanding is that all these values should match. They are called around the same time.
"around the same time" doesn't really mean much. Like I said earlier, if the mag accuracy does not stay at 3/3, you should find a better placement for the sensor without disturbances.
