Jesko is Director of Product Division Photo, Leica Camera. I doubt that the tests himself . No details were mentioned, but what he said makes sense and is expected, unless the in-camera "resizing" is not messed up.

FWIW:
David Farkas said in his most recent M11 video something along the lines of:
-He saw no DR or ISO improvements between 60,36 and 18 MP files with the current M11 firmware ( apparently Leica just released a new bug fix firmware the other day) He said maybe something changes in the future but for now, regardless of marketing, he saw equal DR and ISO across the "triple resolution" files.
-The M11 cover glass is the thinnest cover glass ever used on a Leica M, I guess that means even thinner than the M8? Several of his test images showed really nice sunstars that he thought might be a result of the super thin cover glass
Jesko Von Oeyenhausen said in this presentation that going to a lower resolution means less noise in the shadows (better DR), but that the same effect can be achieved with 60MP if you reduce the resolution in post.
Yes, I saw both videos. Maybe in a controlled lab environment? If I understood correctly, David was just not able to confirm real-world.
I meant how Leica Store Miami determined no DR improvement, did they mean after resize? I understand what Jesko said, most likely at pixel level, shooting at 18M RAW will be cleaner. This has been discussed tons of time here on the forum or even this thread. I am just surprised that we still need visit it time after time
They compared 60MP (LDNG) vs 36MP (MDNG) at pixel level in LR and saw no visible improvement. (They also shared the side by side video showing this)
Did they test 18MP sDNG? Leica only claims an improvement with sDNG.

For 60M downsize to 30M, it will give ~0.7 stop improvement. from 30M to 15M, it will give another ~0.7 stop. This is all therotic value from fundermental oversampling theory. Assuming noise is white/random but signal is the same during oversampling.
I don't know how Leica did it but based on their market material, it seems correct without surprise. We are really approaching something by number here and I will leave those to Bill Claff to do From a rough test I did, I clear saw improvement on 18M file but unsure how it compare to downsized 60M file.
