OLED aging is one of the primary reasons that burn-in is a thing. There's a ton of algorithms to try to normalize this so as the panel ages that it just uniformly dims, and you don't get hot spots (or cold spots). I don't think it's complex enough to handle stuff like the news logos though. Generally speaking it's assumed that the pixels are all exercised somewhat uniformly I think.
