How to determine which live broadcasts have been released and booked via YouTube Data API.

The current Youtube Data API provides the same format for Premier Published/Reserved Live Distribution (data obtained below), and the values of liveBroadcastContent are the same as upcoming, none, live, etc., so it seems impossible to distinguish.

There was a similar question on stackoverflow.com (those who are not jp) and it has not been resolved yet, so I asked you a question.

I would appreciate it if you could reply if anyone knows how to make a decision based on the current API specification that has been released or reserved for Premier.

Thank you for your cooperation.
