Now we see through a glass, darkly...

You can also quite clearly see, in DPReview's DR comparison tool, that the D850 (higher pixel density) yields better results under a +5 or +6 push than pretty much anything else, even when starting at ISO 100.
Again, one must ask the question, is what DP Review measuring actually DR, or is it more aggressive use of NR prior to analog-to-digital conversion? Just because an image is cleaner after being pushed 5 or 6 stops doesn't necessarily follow that the result is an indication of higher honest DR. (Why that is even important is beyond me - if I couldn't get closer than 5-6 stops to desired exposure when shooting, I'd have tossed all of my cameras in a dumpster a looooong time ago.) It may just be an indication of more aggressive NR. There's a reason many Sony sensors are known as "star eaters".
