There's a couple of problems seeing that way:
- we don't have any infrastructure to implement the wallpaper, or
font-smoothing inhibitors.
- there's nothing tell us that changing those settings would actually
make a difference in terms of network usage (do you have that
information?)
- it's way too fine-grained to be useful. Either the link is fast enough
to show animations, or not. The amount of data needed for a static
background image is likely not going to matter as much as the *whole
screen* not giving you 60 completely different images to animate to the
overview ;)

So you could export that information from SPICE, we just wouldn't be
using it in GNOME (yet at least).
