PCA9955B Current accuracy calibration

I'm trying to use the PCA9955B for testing of LED characteristics. The datasheet says the current accuracy is 8% chip-to-chip and 6% per channel on-chip. Are the errors always a constant percent that can be tested and calibrated, then compensated in software, or are they non-linear or temperature dependent?
