Just curious are dim sheets/films that you lay over a display better than just using a software dimmer app? I got a vivo x100 pro that I haven't used yet. According to my mk350n meter the SVM # is 0.03 which is super low but that's with 100% brightness, if I use a dim app it increases dramatically.. so would a sheet make a difference if I used one instead? It's a OLED display
