Sorry, I think you have read the comment in Win32::Console::ANSI incorrectly - quote here in full:
Windows NT/2000/XP does not support ANSI escape sequences in Win32
Console applications. This module emulates an ANSI console for the
script which uses it.
The module is explicitly designed to provide the ANSI console facility on those newer versions of Windows that do not support it. I have tested this and screenshot can be seen here.
