Case 1, non-load bearing wall at midspan. For L/360 and a 15' span you'd expect that the wall would be 1/2" shorter than the end walls that support the trusses.
Case 2, load bearing wall at midspan. For L/360 and a 15' span you'd expect that the wall would be the same height as the end walls that support the trusses. In each of the ~7.5' remaining spans the ceiling would deflect about ~1/4", which can be detected by running a taut line along the ceiling directly under the truss.
