Yes. It has a slight bluish cast to my eye on my calibrated monitor,  
and Photoshop's analysis tools allow me to see the blue in the  
highlights (make a small selection and move it around the screen like  
a sampler, read using the Histogram palette).

Put a 5x5 sampler on the white fur by the cat's nose and another in  
the specular reflection on the bowl. Add a Curves adjustment layer  
and use the white point selector to sample and set a curve on each of  
those points. You'll see that the auto adjustment selected pushes the  
green and red channels to a steeper angle to compensate for the blue.
