Thanks for explaining, I've run into this on my phone in other contexts and I was starting to think my phone screen is having its last days. Turns out it's expected? Usually I run into this when the screen brightness is at the lowest setting.

Screen brightness is usually modulated by changing the strength of the backlight, not the values sent to the LCD cell array. So flicker induces by inversion doesn’t change when changing brightness. (There are exceptions: one could dial up pixel values on a dark scene and dial down the backlight settings to save power. But that depends on the image content.)

  I think some OLED displays don't have backlights? On manipulating the backlight to display a dark scene more power-efficiently: my TV that does this, if there's a small region of constant color (e.g. a TV station's logo) its brightness wavers noticeably as the rest of the scene changes.
