Any app where contrast is very high between background and subject, UI elements and the likes will exhibit this issue, but where it can get for some particularly annoying is videos, video editing and/or graphics work where where the contrast is very high. Add motion to the problem, and you have a ghosting effect where that blooming effect moves with the subject. While maybe not the most annoying thing for the average user, pixel-peepers and those relying on colour accuracy to do their work, will likely benefit from the new screens. Basically, look for anything bright on a dar background and see it has a "halo" (some fuzzy light around the edges). 🙂
