Also, try a contrast of 90 and a brightness of 55 for HD movies/shows. It looks really good.
Here are some settings I managed to get while playing around with my TV. These settings should give you a very saturated picture, especially with the warm 1 color temp set. It may be too saturated, but I recommend it, because it makes the quality look almost life-like, especially when watching outer space images and video. If anyone has a better setting, feel more than happy to post that in the chat, I wouldn't mind checking it out:
Here are my settings:
Dynamic Contrast: High
Black Tone: Dark-Darkest (blacks may seem to dark to you)
Color Space: Native
Color Tone: Standard or Warm1 (calmer, warmer image with more color saturation)
Screen Size: 16:9-Fit
HDMI Black level: Low
Everything else stock I believe.
