Off topic, but I don’t like the “improved” text color. Subjectively, viewing on an iPhone X, it just seems to make the text ever so slightly indistinct, harder to read.
I suspect this is partly due to the “True Tone” feature, where the OS automatically adjusts the display’s color temperature to match ambient light. This makes the “white” background color appear less harsh (less blue) than in most displays, lessening the need for a lighter foreground color to soften the appearance.
Or maybe you could just say that it reduces the perceived contrast, lessening the need for further contrast reduction. I’m not sure if that’s actually true, though. The actual contrast ratio between anything other than black and black should be infinity on an OLED display, or even if you account for a tiny amount of diffuse reflection of incoming light, it would just be a (large) value dependent on the brightness setting.
