Of course we have, since we have high-quality photography of both. Voyager 2 for sure (late 1980s), maybe one or two others (New Horizons?) but now I'll peek and check. During the planning for the Voyager program Sagan et al observed that "the planets would align", or at least their trajectories would be conducive to a planetary grand tour, something that would be much harder for a single probe to do again in the near future. So off they went.

Neptune is fun, but the probe/science interest is much more heavily concentrated on Jupiter and Saturn (general potential of moons to harbor life/habitation potential notwithstanding radiation and whatever else I don't know in detail), large objects to study in greater detail, relatively easy to get to as these things go). I got a nice cheap used book about Cassini/Huygens a few weeks ago, a probe about which I know almost nothing but it's nice to have a basic resource now. Juno, others...

Now that I post pic related (which is a bit dated) it appears that Voyager 2 was the only craft to make the trip to both worlds. Only five craft are leaving the Solar System IIRC.

This slightly outdated graphic shows your 10% figure to be a little low.
