The brass section is very similar to the arrangement used in "Tema da Vitória" that became Ayrton Senna's theme during his F1 career also a Globo TV exclusive track and their most famous theme.
Never heard this theme but it's also similar in arrangement and key to:
and
being possibly composed by Eduardo Souto Neto.
Those were made in-house by Globo's musical arm Som Livre label that had a couple of composers that scored some themes for show openings and telenovelas during the 1980s and 1990s.

Supercine theme also was made in Brazil to the surprise of many chasing the origin of those themes.
