Doubtful. Night Mode will most likely only affect application chrome and menus that use Dynamic System Color [1] named colors, not the actual content within the app (i.e. images, webpages, documents, etc)

Websites will be entirely unaffected as they have they're own custom CSS palettes.

Interesting. I imagined that with a name like "Night Mode", it would be more universal (like Night Shift is). I'll be interested to see how this evolves and whether third-party developers adopt it.
