Seems like it might be an issue with sharpness, though i could be wrong. try adjusting sharpness and see if it makes a difference. Since putting it in game or graphics scene mode seem to make it a bit sharper, thats what your kind of looking for. The 1px difference might just be an occurrence of low sharpness.

The TV Picture mode is set to vivid. Under this configuration I am receiving a desirable result but I am not passing the 4:4:4 Chroma Subsampling tests. The only thing I have not tried is connecting DVI to HDMI from the graphics card. I have not done so as it has been indicated to me that this is not a requirement for amd graphics cards. I am going to try it anyway but would appreciate any comments.
Here are the settings with a similar menu like your LG's. start with setting the input label to PC as you stated.
Picture mode: Game
Backlight: 20/100 (20-30 is recommended for a low light room to save energy consumption. adjust for your preference in a highly lit room)
Contrast: 82 (80-90 is recommended when using full RGB)
Brightness: 53 (50-60 is recommended when using full RGB)
Sharpness: 35 (vary's from TV to TV, but i used a test pattern to calibrate to the exact neutral sharpness without glowing edges. Will be set different if not in PC mode)
Color: 56 (will vary depending on the Gamma setting in the advanced settings menu. 50-60 is recommended for any scene before oversaturation)
Tint: 0G/0R (balanced. should never have to use this setting)
Color Temp. : 0 (D65/6500K neutral white) (use W50 if you're watching a movie)
(if you have any setting under these, like trumotion, it probably gets grayed-out when using PC mode)
ADVANCED Setting (going from what options i have. again most of these are disabled/grayed out when using PC mode)
Dynamic Contrast: off (grayed out)
Dynamic Color: off (grayed out)
Noise Reduction: off (grayed out)
Digital Noise Reduction: off (grayed out)
Flesh Tone: 0 (grayed out)
If i missed anything between these, they are most likely grayed out too
Gamma: Low (medium is really 2.2, but to correct for Xbox 360 gamma, i have to use Low which is 2.0)
Black Level: High (High for Full RGB from your computer or game console, low for limited range from a DVD or VHS kind of device)
Real Cinema: off (grayed out. Disable PC mode for this to work in Movie picture mode)
Color Gamut: Wide (grayed out)
xvYCC: off (grayed out)
These are MY certain panel's correct color calibration. im just giving you an idea of the similar results you might set if you use test patterns to calibrate your display. Lagom.nl/lcd-test/
is a good site for doing so. As far as 4:4:4, you did everything right so far. If it looks off play with sharpness, if it still won't pass, then the TV doesn't support it then.
