The thing is, it's not obviously wrong.

Depending on what video hardware you have, and what drivers are built
into the kernel, it might be a classic VGA 80x25 8 dim + 8 bold colour
console, a 256 colour palettised frame buffer, a 24-bit direct-colour
frame buffer, or fully hardware-accelerated 3D. There's no way for a
single terminfo database entry to represent all those possibilities.

The documentation for the Linux console, console_codes(4), only
describes the capabilities listed in the "linux" terminfo entry. Note
that among other things, the ponysay source has a lot of mentions of
"KMS", or "kernel mode setting", the same API used by the X11 and
Wayland display servers. That stuff is *well* outside the range of what
terminfo is appropriate for.
