I know most recent Pentax cameras are ISO invariant and I expect the

Does this mean that you don't get any advantage from shooting a higher iso
rather than under exposing at a lower ISO?

Very interesting. I'll have to study these in more depth when I'm not
packing for a track day. Thanks.
I can think of one reason to not just shoot at base ISO. Lightroom only
allows a few stops of exposure compensation, and it is very easy to
exceed that range.
It does seem, however, that there is little downside to picking an
exposure triangle in manual, that may be a stop or two under to preserve
highlights, and effectively do your Tav adjustment in post. This will
be very helpful when photographing at the dojo.
I have noticed that when I bracketed in Tav mode, by the time I finished
adjustments the differences between the exposures were very subtle. Now
I better understand why.
There is some fun physics to learn here in order to optimize sensor
performance.
