Matixsnowwrote a review of Shimano XT BL-M8000 Disc Brake on April 11, 2019
Not sure why no one has mentioned, but the m8000s have a very inconsistent bite point. The first lever pull comes close to the bar, but then quick repetitive lever pulls fall much further from the bar. This is much more noticeable in colder temperatures. It sounds like the new XTR brake has similar issues. I've bled, re-bled and have others bleed my brakes, I even purchased a second pair of these breaks and they all have an inconsistent bite point. I'm in the market for a new brake.
