I know this well since my last 3 BMW's have been either SMG II, SMG III or M-DCT

I don't agree with this assessment. I find that it rev matches perfectly without driver assistance. In fact even on the track at high rpm I found many times I had to look to see if it had downshifted or not (because of the downshift ignore issue) because it was so smooth I couldn't feel it in the seat of the pants under hard braking. I don't feel any downshift driveline jolt because the downshifts aren't perfectly matched. However, I do think the amount of downshift blip is dependent on which S setting you have selected.
I'm not discounting you have a lot of SMG/DCT experience, I just haven't felt what you're saying.
