Apparently just because the default iOS calendar app does not allow editing a calendar does not mean that it cannot be edited via API. Probably need to be mapping the "Immutable" property rather than "AllowsContentModifications."
Case in point being "US Holidays." That cannot be renamed in the Calendars app, but it can via EventKit. (so it is inappropriate to report CanEditCalendar as false)
