They fundamentally don’t but a high quality / high refresh OLED display can come very close and if implementation done right IMHO can even surpass experience in some cases. I still play old games on my old beloved tubes but to be frank often just for purity / nostalgic reasons and because I like the original 4:3 format without (“perfect black” even) overhead on the sides. I hope Apple will finally Switch to OLED for their iPads as the aftermarket / replace displays for those usually are well affordable and usable for e.g. a wall mounted “cabinet”.
