Wahoo Kickr Power Meter Drift

Is there any way of looking at the Wahoo Kickr’s change in spin down calibration data over time? I have Assioma pedals too and the two have moved from pretty close to each other to a 3% difference. Over the same time my own performance on the Kickr’s version of my power is a bit too good to be true (would love to think its not), making me doubt the Kickr. I’ve not seen anything obvious in the App that shows the Kickr’s data but thought I’d ask, especially as I’m suddenly in cat A if it’s right!
