I think that the main thing learned is that there is an advantage
to guessing at the proper WB preset or use Custom WB where the
white point is very warm or very cool in order to help avoid
clipping the red or blue channels, respectively.

Hmm, not that I'm not willing to accept the fact that WB influences
analog gain for single color channels previous to A/D operation -
even if that is surprising news to me - but what I'd really like to
see are real world examples - real pictures! - that demonstrate
tangible advantages of Custon WB or preset WB over Auto WB if
shooting in RAW.

I always use Auto WB, shoot only in RAW, and honestly never was
conscious of any WB problems in PP.

Not for panos... do you?

If I find time I'll try some real world tests myself, but unless
those results shows convincing advantages (or someone else can
demonstrate convincing results) I'll stay with Auto WB and RAW for
the time being.

This is the real question, isn't it? What can we do withthis new knowledge (except of stop saying that the WB setting doesn't affect the raw file)?

Second thing I wonder is why Nikon advertises its color channel
gain control as advantage of their technology - and Pentax,
implementing that in their rather old "Ds" model, does not talk
about it at all ...

One consider it a good thing, one consider it something that would confuse their entry level customers?
