No.  http://dev.w3.org/csswg/css3-images/#color-stop-syntax currently says:

   Between two color-stops, the line's color is linearly interpolated
   between the colors of the two color-stops, with the interpolation
   taking place in premultiplied RGBA space.

and there was related discussion on www-style, iirc.
