I was just looking at that video you posted at the beginning of this thread and there is nothing like that now. I had several specific instances of the issue - web sites such as Macrumors that have a dark setting, and native apps such as Mail and Settings. With those apps even when dark mode was off I would see yellowing in the contrast between the black text on the white background, with night shift and True Tone on. When dark mode kicked in I have night shift scheduled to go off but those 2 apps would now have the white text on the black background like those web sites, and smearing, yellowing was particularly noticeable. Right now dark mode is on, night shift is off but True Tone is still on and there is no yellowing, blurring or smearing on those web sites, nor the native or 3rd party apps that have white on black text. All that is gone now. For right now, and understand this is still a beta, the issue is fixed, for me at least.
