Element.OwnerView would work with a ScheduleSheetInstance, not a Schedule View, since the schedule view itself is not technically the element on the sheet.
You would have to
- Collect All Elements of Type > Schedule Sheet Instances
- Get ScheduleId property with Python (or Element.TryGetPropertyValue from Wombat Dynamo)
- Get Schedule Element by ID from the ScheduleId property to filter schedule sheet instances by the schedule view you want
- Get Owner View from filtered schedule sheet instances
