It's quite simple actually. In 99% cases (all official stuff related to Sound! Euphonium novels, manga and anime) it will be. Other cases include and Creative  Commons licenses, CC-BY-SA 3.0 or CC-BY-SA 4.0. For example, some photos of instruments I posted are licensed under CC-BY-SA, because they were posted on Wikimedia Commons under it.
