Manual WB does impact *istD RAW

You were right. The first curve below was with a manual WB shot at a deep red chair. The second shot with a light blue folder cover.

So, it looks like the *istD does not change the raw values in the preset WB modes but does in the manual mode.

However, I notice that it does not do what I had hoped it would - that is extend the DR. The highlights of at least one color still saturate at about 3 stops above meter reading (EV = 8). In fact with the light blue card I lost 1/2 stop.

The curves look as though you might find a color of card that would extend the highlights by about 1/2 stop. But not worth the effort in my opinion.
