    There are two RGB OLED spectral correction modes:

    1. RGB OLED (Sony PVM-2541)
    2. RGB OLED Family (Sony PVM-2541, Samsung Galaxy S7, Lenovo LEN4140)

    What exactly is the difference between the two?

    I have an HP Envy X360 15,6″ with a Samsung 4K AMOLED  display and I’m confused.

    Plot spectral power distributions, they are very close.

    Could you please elaborate?

    Select an spectral correction, press information buton on the right, see spectral power distribution stored on that correction.

    They are almost the same: RGB OLED.

    So it doesn’t really matter which one I choose?

    Yes, 2nd may be closer but unless you make a custom one it’s guessing.

    I’m trying to measure the Adobe RGB coverage of my laptop’s display, using an X-Rite i1 Display Pro Plus.

    The RBG OLED Family correction mode gives me a slightly higher reading than the non-Family one (the difference is 1-1.5%).

    Which reading should I trust?

    The one that makes RGB 255 white on MS paint look whiter. ABL may kick in if patch is too bigg (and that alone is enough to avoid OLED laptops for serious color work)

    Again, thank you very much. 🙂

    I will try the Paint method and report back.

    The RGB OLED Family mode makes colors noticably warmer than the non-Family one.

    Does it mean that the non-Family mode is the one that gives me the correct reading?

    Also, I would like to talk about ABL.

    I calibrate my display using an X-Rite i1 Display Pro Plus and CC Profiler/i1 Profiler:

    Luminosity: 80 cd/m2

    White point: D65

    Gamma: 2.2

    Tonal response curve: Standard

    Contrast: Native

    I always achieve my target values (actually the color temperature is about 6450K). There are no issues. The QA check goes fine. My average delta E 2000 is 0.6-0.8.

    I recalibrate the display weekly and so far I may have performed 20-30 fully-successful calibrations (I got the laptop in early July).

    Could ABL still be a problem, even though CC Profiler calibrates the display without issue?

    That means that since you have not a custom CCSS, the higher error caused by not using a custom one will be on white point.

    Yes, but it is up to vendor firmware how fast it kicks in (patch size + brightness). Since it is not specified on consumer doc… it’s trial and error.

    So after all, which reading should I trust? Because I’m still confused.

    Unless you can get a custom CCSS for your model.
