Yeah, I think this is actual video stream CC, which I didn't know Blu-rays supported. Afaik, most DVD releases do CC both with the standard DVD subtitle system and the traditional CC system, but traditional CC use the white text on a black background, like you'd see on TV in a restaurant. That method is handy for people who are both hard of hearing and have low vision (like older people) because the subtitles are easier to see.
But looking it up on wikipedia, supposedly Blu-ray can't handle the old CC system at all. Odd.
