Is there a way to disable this specifically for PDFs?
I do have this setting on (e.g. for Markdown) but cannot use PDFs for whatever reason in dark mode.
It would be nice to learn how to return to previous behavior:
Not yet. We might add a hidden preference to the next release.
That would be super helpful!
Cannot use dark mode any longer at the moment 
Another potentially useful feature would be Sepia mode. A fine-grained dark mode would also be fantastic!
I think many more people will request that. I use Devonthink with a lot of PDFs and dark mode is particularly challenging for them, especially magazines and similar publications.
Great update!
Unfortunately the PDFkit’s dark mode support is not customizable, it’s just on or off.
The dark mode of PDF is finally here. Thanks to the developers, especially for retaining the primary color of the pictures in the text version of PDFs, which is great.
But this may cause some problems? mainly scanned or OCRed PDFs, most of which cannot display the dark mode normally (still white).
The following are some special cases
Pure text version
In order to show more content, set it to Two Pages Continuous.
The text part is darker than the blank part.
Scanned version
The pure black part of the rectangle are pictures. These pictures cannot be displayed normally.
I’d also like to see a toggle for this setting.
