The list of countries represented at the Berlin Conference is public and easily available on Wikipedia. Obviously, out of the 14 countries represented, many of them were not great powers (Belgium, Denmark, Portugal, and Sweden-Norway stand out here as second-rate powers).
But Belgium is not a great power with a modern fleet, and they arguably ended up getting more than the Germans. Portugal was in quite a similar situation to the Ottomans - both were declining powers that previously held territory in Africa and actually lost it at the expense of African powers (Egypt for Ottomans, Oman for the Portuguese). Portugal also received territory at the Berlin Conference.
A priori, I'd argue that the Ottomans had a more realistic case for gaining territory than either of those two, who actually did gain territory. In that sense, I would say that the Ottomans gaining territory would not be a shockingly unrealistic outcome if the diplomatic situation was favorable to them. There's a pretty decent argument that Belgium and Portugal were the least significant power represented at the conference, and both of them were big beneficiaries.
