The highlight clipping can be a function that can increase dynamic range even further without adding to the file size needed to store all the extra bits. The Prime engine does a good job of that now, even among the competitors, as many still try to circumvent by using raw.
I think you are correct that the Pentax/Ricoh image processing does an exceptionally good job of squeezing as much DR as possible within the current 14 bit RAW image, though I think the conversation has been about what extra
would might be achieved with 16 bit architecture. Clipping the highlights does not increase the DR, but preserves the shadows.
I think the aim is to prevent
highlight clipping, which the latest sensor may achieve;
- if the analog/digital converter has 2 more bits of resolution,
and
- the photosites can hold a sufficiently large range of electrons,
and
- the the gain of the analog output from the photosite can accurately match the input range of the adc so that black is 0000000000000000 and white is 1111111111111111
..(or more accurately, each of the red, green and blue components of white)
then you can theoretically have 4 times as many steps between black and white, while not clipping the highlights or losing the shadow details.
In practice I suspect that signal noise will prevent all 16 bits being meaningful for a single exposure.

Any Japanese speaker make better sense out of :
来年発売予定のPENTAXの"APS-C判最高機種"ですが、夏前に発売されればいいなあと期待していたものの、"その予定"より少しズレ込んで、ひょっとすると夏過ぎになる予感もしないでもない。
出るぞ出すぞ、と言って、なかなか出てこない「狼少年PENTAX」の面目躍如? 我慢して待つしかないか。
