Power BI REST API -- getting report page metadata

I'm looking to get page info for a specified report via the REST API.

I found an undocumented endpoint at https://api.powerbi.com/v1.0/myorg/groups/{group_id}/reports/{report_id}/pages, but that only gives me the following fields:

Name
displayOption
width
height
order

I'm looking for the page name that gets rendered on the report tab. This can be attained by using the javascript client API as evidenced in the Power BI Embedded Playground, but since I'm using the REST API for all the other data it's a bit of a pain to have to use two different technology stacks to acquire this information. Is there a way to acquire this information solely via the REST API?
