DW3000 - is Detection threshold avalible?

On the DW1000 the leading edge detection threshold is available in register 0x2E:00
I was using the ratio between this threshold and the received signal as one of my quality metrics.

On the DW3000, as was the case with the DW1000, there are various registers used to set the threshold as a function of the noise level. However I can’t find any mention of a register to report what the threshold used ended up being.
Is this available and I’ve missed it or is it not accessible on the DW3000?
