Same ACR, same non-NR, non-sharpened export resampled to 16MP and exported JPEG baseline max quality.

How do you know the same ACR algorithm is used? Have you audited the source code? ACR uses different algorithms, different defaults and different processing settings for pretty much every camera - by necessity since the RAW files are very different - and there is no explicit attempt to create comparable conversions between cameras.

Indeed, it would be futile to try to make comparable default conversions since sensors do not respond linearly to changes in circumstance. Everything from color separation, noise reduction (yes, ALL sensor arrays employ noise reduction in consumer cameras, no exceptions), gain and linearity in read-out varies, so there is no baseline to start from.

There are, again, too many uncontrolled variables to draw any kind of conclusion about what is actually going on.
