Reverting does not depend on whether the override happened in a \with
expression or with an explicit \override. However, the overrides in
context definitions and \with expressions _accumulate_ on the stack
while normal \override _replaces_ the topmost override.
So if you want to get back a _previous_ context-specific value (many
grob property values are just established as global defaults and are
impervious to reverting) through reverting, you need to use
\temporary\override instead of \override.

If there _is_ a default value, reverting should get you there.
Here is an example for accumulating overrides:
\layout {
\context {
\Staff
\override NoteHead.color = #red
\override NoteHead.color = #blue
}
}
\fixed c'
\new Staff \with {
\override NoteHead.color = #green
}
{
c1
\revert Staff.NoteHead.color
g
\revert Staff.NoteHead.color
e
\revert Staff.NoteHead.color
c
}
