Is the issue DPR, or is the issue ACR assignment of specific default adjustments on import?

It's a little bit of both. DPR will say, if you reset the camera to its defaults, and take an out of camera JPEG, or a RAW and process it in the same program without changing any settings, then that gives a good indication of the what the camera's image is like. (With the kit lens, under artificial light, indoors, on a tripod, shooting a still life).

about this:

Anyone who has used a Pentax knows the cameras, by default, apply the least sharpening of any brand, and "defensively under-expose".

for it's JPG's

It appears the Nikon wants sharpening of +40 and ACR / Lightroom accepts that setting from the RAW file.

that is my point: my LR default settings for my Pentax RAW files get changed do to the XMP file, where the sharpness is set to OFF (=0). Don't think that this is done do to my Pentax RAW file, it is done via the XMP file, which is included in the RAW file, when you download the Pentax RAW file in this comparison tool. That's why I used my EXIF tool, where I can delete this embedded XMP files...for to see where my LR behaviour comes from. So without the XMP file my LG use for my Pentax RAW file it's normal default settings and for the sharpness amount it is 25 (and not Off (=0).

The camera does not create an XMP file.  In lightroom the database holds the processing settings for each file, and the DNG files are not changed. Lightroom will read an XMP file if one exists (but only writes an XMP if catalog settings tell it to). .

If you open a DNG file in photoshop, it uses the Adobe Camera Raw extension, (ACR) which can either update the DNG file with the processing settings OR write those settings to an XMP file. The settings button configures what it does with DNG. PEF or NEF files can't be changed so those always create an XMP.

I'm seeing files set to portrait or B&W on the K1 import with sharpening +40 and colour NR 25 in lightroom and Photoshop.

I have not this ACR, therefore I don't know if the sharpness of 40 is normal (the default value) for the Nikon, but I don't think so, because in the ISO 6400 RAW file of the Z 9 there is used a little different sharpness value than.

People can (and will) argue at length whether camera defaults are a true base line, or if different steps are needed in ACR / Lightroom for each camera to give comparable results. Those of us who go back a long way with DPR will remember the "Canon sharpen a lot, Nikon sharpen a bit, Pentax don't sharpen" arguments 15 years and more ago. If they change their methods it means you can't do a comparison with and old test (it might have been meaningless but changing the method means it is meaningless for sure).
