Thank you for your work.

I'm bit surprised that charts for R6 II converge only at about ISO 1600. Some people here claim that 14-bit vs 12-bit becomes irrelevant above ISO 400, but this seems not to be a case. Or maybe I'm misinterpreting the chart?

Where the numbers converge and what people actually observe don't need to match.

And one more thing. Some cameras drop to 12-bit readout even in mechanical shutter (e.g. Sony A7IV in compressed RAW required for H+ speed in AF-C).

That's true.

Do you know how this impacts DR? Would it be similar to Canon R6 II electronic shutter vs mechanical shutter?

There is an impact but not one I have measured.
