The 'label' would have likely atrophied. Kittens raised in an environment without vertical lines don't develop the ability to perceive vertical lines. These sensing cells would have developed in the retina, but it seems reasonable for the same effect to occur on any cells that are tightly connected with vision - such as colour qualia. Though I doubt that many neurobiologists take that philosophical term very seriously.
