Your thoughts? I'd just love to see a practical example, that's all.
With SP2/SP3 there is almost no point of changing QM, because with AQM=ON encoder will change you matrix anyway. Quite often at the end default matrix became FOX one

You may try to lower Activity to 4 or go much higher eg. 48.
With some noisy sources SP3 tries to hard and when it can't preserve all details it does blocking (like on your sample grabs). It means it's to sensitive for all smallest noise, so you can try to rise Activity setting. In the same time it may start producing mosquito noise when Activity is to high
