Thanks, that's interesting stuff.
Another interesting question somewhat related to HPS is, if there would be any forced RAW denoising kicking in at a certain ISO threshold, or not.

to the best of my own + forum knowledge there is no such high ISO denoising with Nikon. (Sony cameras have been known for such denoising applied to a then ironically called "cooked raw") . Nikon high ISO NR applies to jpg only, 'long exposure NR' is a built in black frame subtraction which can be turned off by the user. This subtraction requires a wait time equal to exposure time: potentially annoying.

Nikon does have High ISO Noise Reduction that can be controlled by the user and can be set to OFF.
When it is active it affects NEF as well as JPG files.

This is separate from the Long Exposure Noise Reduction (LENR) that you mention.

Furthermore, some Nikon models (not the D7200) perform Noise Reduction on the NEF (and JPG) that cannot be disabled based on the length of exposure.

Here's an example I documented for the D90: D90 Does Noise Reduction on NEFs at Longer Exposures
