After some rigorous checking:

• It's not a sudden dip
  
• The rim is ~1mm closer to the right hand side of the bike at the valve than it is opposite the valve
  
  

Should I not be able to feel that?

Definitely not trying to freak you out, nor am I an expert on expensive carbon BUT isn't deep carbon rims supposed to be really stiff. And if so, wouldn't there have to be something quite wrong with the spoketension if the wheel is out of true.

I've heard stories of people having trouble truing wheels with B43 rims and the like because those kind of rims are very stiff and don't show their "out of trueness" very well. They then ended up with spoketension not being very equal and therefore a weaker wheel.

I suggest checking the tone of the spokes individually just to check weather there are a couple which are way of.
