What is the latitude of color correction on the black

I was just wondering how many stops can you get back with the black magic camera. I was shooting in bright sunlight 2 days ago and could not see the monitor at all on a couple of shots. going from sun to no sun. A few shot were very blown out but when I got back and color corrected the information was there. So the question is how many stops over and under can you be before there is no information?
