Adam, Ralf, if I understand you correctly, it means that overexposure
blinkies of both my camera(s) and LightRoom actually start blinking not
at pixel value of 255 but somewhat prior to that. And then, you and also
Adam say that whatever the minus exposure compensation I am dialing in
in LightRoom to make those red blinkies disappear has nothing to do with
actual sensor dynamic range? Is that so?

What you say, Tim, makes perfect sense. But outside of Pentaxia, there
are cameras and sensors that have more headroom in the bright areas.
There is no way of extending the range beyond the point where all bits
are set to "1". Not with Pentax nor with any other manufacturer.
All you can do as a manufacturer is set the camera in a way that it
deliberately 'under'exposes a little and hope that the shadows won't be
drowned in noise.
Now, if other manufacturers could hold back a little more on exposure,
this is mainly due to the fact that they haven't been using this rotten
Samsung sensor we have been plagued with for two camera generations.
