I'm not sure, myself.

The only mention of NCURSES_EXT_COLORS I can find in documentation is
in the NEWS file, where it just says that it means "extended colors"
are available:

https://github.com/ThomasDickey/ncurses-snapshots/blob/a9b714f69879e6e8313c116eeee474998e0583fe/NEWS#L5225

Searching for "extended colors" finds a paragraph in the INSTALL file,
which says that "extended colors" means supporting 88-colour or 256-
colour terminals, and is part of ABI 6:

https://github.com/ThomasDickey/ncurses-snapshots/blob/master/INSTALL#L1709

This confuses me, because I've definitely been using the xterm-256color 
terminfo entry for a lot longer than Debian has used ABI 6.
