I've read all the thread that pushed you to differ from the reference suggestion BT709, and it seems strange to me that software/hardware houses would so massively default to BT601 when the reference says different. I'll do test if i have time.
Your reference iso13818-2.pdf is outdated. In "ITU-T Rec.H262 (2000 E)" they state:

In the case that sequence_display_extension() is not present in the bitstream or colour_description is zero the matrix
coefficients are assumed to be implicitly defined by the application.
