You can invert PDF by pressing "i" or set it globally with `(eaf-setq 
eaf-pdf-dark-mode "true")` (details and other customization options can be 
found in [1]).
You're right about EAF doesn't support setting slices or synctex, but it could 
be implemented in the future. ;-)

Where to draw the box of the graphic content (QGraphicsView) is entirely 
determined by a Lisp function. I can imagine a similar function that displays 
the box similar to lsp-ui popup doc, then IMO that's a way to embed something 
into Emacs buffer. However if we want the text to move out of the way so that 
it's not overlapping with QGraphicsView, it would require additional effort of 
modifying Emacs' code.
If you want, you can have a look at the architectural overview in the EAF wiki 
[2] that might help your understanding of EAF's design.

That's alright. EAF should support wayland now, though we do not have a lot of 
people who use EAF on wayland that come back and provide us feedback. I 
personally use KDE and don't have many chances to test EAF on Wayland or other 
DE/WM.
