These findings are interesting from a technical perspective.

The main questions I have is how much difference does this make to the level of detail in the raw files compared with for instance the Leica and what are the benefits / drawbacks of doing this?

In real world use, will we even notice?

Engineers fine tune the output from every camera. The goal is to produce good looking and easy to post process images. Guess we do notice even when we are not aware of noticing.

Completely uncooked RAW files are ugly and need a lot of additional post processing. Some who want uncocked RAW do probably not quite know what they wish for.

One area where the noise reduction might be problematic is deep-sky astrophotography, where faint parts of nebulae etc may not even show up visually in individual exposures since they are so close to the noise floor. Stacking tens or hundreds of images can be needed to reveal them in usable quality. Doing unpreventable noise reduction for the individual images may smear these faint parts.

Then again, I don't recall seeing real-world complaints about this so maybe it's less problematic than I fear.
