Similar dark backgrounds can have different causes
A phone with light text on a dark background might be using a standard dark theme, colour inversion or another display treatment. Google distinguishes their scope. Identifying the active control is useful when the programme itself suddenly looks like a negative image while the surrounding interface seems acceptable.
Inversion includes media
Google says colour inversion applies across the device, including media. Standard dark theme applies to the system interface and supported apps without changing colours in media such as videos. A picture altered by inversion is therefore a different observation from a normal dark app interface. Do not assume both modes preserve the programme’s colours identically.
Check the setting before the stream
Inspect Android Accessibility, Colour and motion, Colour inversion using the route available on the phone. Note the current state. If inversion was enabled unintentionally, a brief comparison with it off can answer whether it explains the colour change. Preserve an accessibility preference someone intentionally uses rather than treating every altered colour as an error to remove.
Do not conflate the expanded theme
Google also documents an expanded dark-theme option on newer Android versions, with possible image and legibility effects. That is another named setting to inspect. Changing inversion and expanded theme together makes the result difficult to interpret. Record one setting difference at a time.
Report the scope of the change
Check whether menus, posters and the programme are affected, then state which display mode was active. If the entire device is inverted, resetting a player account or changing the programme quality is unlikely to answer the right question. A precise display-state observation helps separate an intended accessibility transformation from a media-source issue.
