Hi, I think these podcasts were incorrect. I just now tested it out on an iPhone 5 running the latest version of IOS. Turn brightness up to 100%, invert the colors in accessibility, and then turn on screen curtain. If you have enough vision, you can see light on the screen. Lock your phone, and the light turns off.
