> As long as their database in docker is being incrementally updated (using the same migration scripts as on production which only apply new ones) is this hit only when spinning up a clean docker image?

Yes, but being able to quickly return to a known-good state by trashing the database is still useful because getting migrations right without testing them is hard.

Using named volumes helps because they don't need to be bridged through to the host filesystem.
