You are correct. If you tune a string to a higher frequency, all else remaining the same, you decrease the inharmonicity. On the other hand, if in the scale design, you increase the diameter of the plain wires (and core wires of the wrapped strings), tuning the strings to the "correct" frequencies, all else remaining the same, you increase the tension, as well as the inharmonicity.
