Yes, the write ops for changing an entity depends on how many indexed properties you change. It is: 1 op for the entity 2 ops for each changed index value (1 to remove the old value and 1 to add the new)
Since it is not a fixed value and depends on what you actually modify, we do not (can not) show it in the dev_appserver's Datastore Viewer.
