I mean, they're also woven differently. Like damask is reversible because the warp and the weft contrast? The backside is the inverse of the frontside. But you can't turn brocade over because the pattern is woven only with the weft, the back's just loose threads and garbage. But if you're buying clothes, the tag's probably just gonna say "jacquard" since they're made on the same kind of commercial loom now anyways.
