In both Terminal.app and iTerm2 with notermguicolors, the terminal
background is set to Vim's background, as you say. Not all of the 256
colors look right, though. Attached you find a screenshot: the
colorscheme is Solarized 8, although the particular colorscheme should
not matter. See how a few of the 256 colors are out of place, and also
a shade of gray is wrong. Of the system colors, Normal White (color 7)
and Bright Black (color 8) are grey instead of Solarized white
(#EEE8D5) and Solarized black (#333344), respectively. Note that this
is what I see also in iTerm2, so this does not appear to be
a terminal-specific problem (or, both terminals have the same issue).

In iTerm2 with termguicolors, the terminal does not seem to inherit
the colorscheme's colors, but it appears to always use default colors
(the 256 color palette looks right in this case). In particular, the
background is always white or black, depending on the value of
'background' at the moment the terminal is started. See the other two
attachments. This is also what I see in MacVim.

Finally, I have tried NeoVim's terminal for comparison, and colors
appear to look right under all circumstances. So, it is definitely not
"impossible" to correctly set all the 16 system colors (but, maybe,
NeoVim is doing something hackish?).

Life.
