But raytracing isn't about that. Its about more accurate reflections of light which lead to more realistic mirrors/bounce lighting/etc. Your resolution or hdr/dynamic contrast/whatever will certainly help a bit, but no, the benefits of raytracing are apparent across all screens. Watch every toy story on the same screen and tell me the lighting doesn't look better each sequel. Same thing.

What do oled or qled have to do with raytracing?
