Under display settings, there’s an option to customize the color vibrancy on the Deck OLED, with a slider ranging from “sRGB” to “Native”, set to the middle by default.
From what I understand, sRGB is the “most accurate” color setting, while “Native” takes advantage of the screen’s ability to display colors outside of the sRGB range, resulting in that “pop” in vibrancy.
My question is, what settings are you all using? Are you sticking with the default, toning down the colors a bit, or turning them up to max?
Put it in srgb mode, all the way to the left. Sdr is made for srgb displays, so you need to clamp a dci-p3 display like the sd oled screen to srgb for accurate sdr colours.
Anything else is objectively inaccurate and will give you a “boosted” vivid mode image.
