MQA is not mastering but removing unwanted artefacts from digital gateways as I understand things, thus revealing the master for us to enjoy, free from said artefacts.

My guess is that you are referring to the correction of ADC flaws. If that is the case then it does not apply to more recent ADCs which have considerably better performance. I do not know at what date ADCs ceased to need this rectification but I expect someone else will know.
