Accurate sensor dynamic range measurements

I'm hearing a lot of discussion that with the R5 sensor, Canon's dynamic range has finally caught up to Sony. But that is not correct. Canon is using mandatory, baked-in noise reduction to get higher numbers in testing by blurring away noise. But you could of course do the same thing with Sony and modified-Sony sensors in Nikons, Fujis and Sony mirrorless cameras and get even higher DR numbers with less loss of detail. And the noise reduction algorithms possible in powerful computers without time constraints are far superior to the firmware noise reduction algos that must process an image on low powered processors in ~1/100th of a second.
I think people want Canon to have "arrived" therefore they have decided Canon has accomplished the feat of catching up with Sony. But the unavoidable noise reduction simply proves that they haven't.
