This TV only supports 4:4:4 Chroma in Game/Graphics scene mode, in all other modes only 4:2:2 is supported. I Just found this out a few months ago after running a chroma test image. I always knew the picture clarity/sharpness is General/Cinema modes were worse than Game/Graphics modes, but didn't know about Chroma sampling until recently while researching HDMI and 4K support. Now That I know this information I now only watch Videos/Movies in Graphics mode with LED LED Dynamic Control: Standard and i/p Conversion Preference: Quality which enables CineMotion: Auto 2 to reduce judder in 24p content when not inputing a 1080/24p
signal to the TV. The added clarity/sharpness is worth it, but you will notice backlight clouding/flashlighting more depending on content(letterbox movie) or if your TV has these problems already.
I also found that LED Dynamic Control: Standard would crush detail in dark areas in Video Games and the TV's local dimming isn't fast enough when playing games and can cause distractions or too dark of an image so I recommend a setting of LED Dynamic Control: Off.
