As the title says I bought a Apple TV 4K didn’t even know my tv supported Dolby Vision during setup switched to Dolby vision and wow it’s like I replaced my TV the video quality and picture quality is night and day compared to my old android boxes. That’s all thank you.
That’s the HDR kicking in! The show may be more dim, but it will have much more accurate colors and you are viewing closer to how the director intended.
