    The V20 delta grayscale accuracy: 8.40 (Terrible)
    The S7E delta grayscale accuracy: 1.82 (Second best Android on this metric) (Winner)

    The V20 delta color saturation accuracy: 4.70 (Average)
    The S7E delta color saturation accuracy: 1.32 (Best Android on this metric) (Winner)

    Lower is better on both metrics. The OEM's that attempt to properly calibrate their displays will typically be less than 4.0 on both metrics. The S7 Edge is the best in the game on the Android side of things, though the iPhone 7 Pus is the actual champion right now of display accuracy.

    The V20 average white point in K: 9257 (terrible)
    The S7E average white point in K: 6508 (Amazingly good, best in the industry)

    On the average white point, 6504 is "perfect" and everything is ranked on it's deviance from 6504. On this metric the S7 Edge is 4 away, while the LG V20 is 2753 away.

    Recent phones that do well on color accuracy are: Galaxy S5, S6, S6 Edge, S7, S7 Edge; OnePlus 3 & 3T (in sRGB mode), Nexus 5X, 6P (in sRGB mode on the latter), Pixel & Pixel XL (in sRGB mode), iPhone 6 series, iPhone 7 series, HTC 10 and to a lesser extend the 2016 Moto devices in a specific display mode called "standard".

    So those 25 or so devices all have substantially better displays than the V20, V10 and G5. The LG G4 was the last one to have an "average" display and it was slightly below average.

    Some third party analysis by Android Authority: LG V20, G5, Note 7, S7 Edge: Display Showdown - Android Authority In the section entitled, "Ouch, it’s poorly color calibrated" they state:

    "Things don’t get better for the V20’s ability to accurately reproduce colors in the sRGB color spectrum chart, where it just fails to hit the reference points within the boundary. Sad to say, it manages to hit only one single target, but fails miserably with everything else. Bringing your attention to its color gamut chart in the sRGB spectrum, you can see how all the colors are inaccurately produced.

    Yellows seems to be influenced by greens, while magentas have a hint of blue in them. Even worse, the V20 can’t even properly recreate the color teal, which is arguably the easiest color to reproduce out of the bunch. Honestly, it’s pretty rare for a display to botch the color teal, but the V20 does exactly that – wherein teals creep into blue territory.

    Now, it’s one thing to be overblown and saturated, but there’s no consistency to the V20’s color path. For those who are particular about color accuracy, the V20 is an unlikely candidate, due to how it just can’t produce realistic, true-to-life colors. Well, it definitely shows that the V20 follows after the G5, seeing that the two results are nearly identical.

    Over on the AMOLED side, Samsung’s offerings are close to perfect as they come when it comes to color accuracy – albeit, you’ll need to set the display to basic mode."

    That section follows the section called, "Unbelievably cold color temperature".

    Phone Arena concurs, labeling the display's Color Temperature "Poor", Color Saturation Accuracy "Average" and Grayscale Accuracy "Poor".

    Long story short, from an objective standpoint, the LG V20 display is terrible. That by no means indicates that people can't enjoy it, a whole lot of people don't care at all. But that's how the measurements break down.

    For color accuracy, it really comes down to being able to reproduce or match color gamut used for producing the content being viewed. OLEDs typically...but also do not necessarily provide a larger color gamut than IPS LCDs; this depends on how the OLED produces color (white OLED plus color filters, or separate RGB materials). IPS LCDs are also capable of very wide gamuts; for example, with the V20 High Contrast enabled that effectively turns on the full potential of the RGB LED backlights. Those results would have been different otherwise if the High Contrast was enabled. The G5 also has a similar setting mode. The LG Display colors are typically calibrated to adhere to the DDC/CI standard which would better explain why the defaults are always slightly off. I have dig it up.

    1) Show me an OLED being used on a phone that does not have RGB subpixels (not talking about specific arrangements).

    2) Show me evidence of the V20 using RGB LED backlighting.

    3) Nothing you said refutes any of what you quoted. LG can have all the tech they want in their displays, but they aren't calibrating them at the factory for color accuracy. I doubt there is anything you can say to refute that fact.

    4) DDC/CI is not a color standard.

    5) Android as an OS does not support anything outside of sRGB, so it does not matter if the display can do better than that or not.
