Simply put, everything that will be exported to the outside ( content, Echo, printf, and so on) will be captured, no matter what you are include or what you are, without exception.

But note that ob_start it is possible to overlay the call, if include the file is used internally ob_start / ob_end_* , the external is not captured. See the official PHP documentation.
