sigh... Simple:

Not as simple as you say.

The color gamut triangle of
the ATSC *standard* - what the STANDARD
is capable of reproducing -

ATSC has no standard color gamut. Even with caps-lock, there is no
STANDARD color gamut in ATSC. Rec. 709 is common for HD programming,
and Rec. 601 is common with SD. But ATSC doesn't care; the primaries
and the white point are specified in the stream. Maybe someday Rec,
2020 will be standard in a future version of ATSC, but for now, there
is no such thing as an ATSC standard color gamut.

is a tad smaller than that of NTSC.
