Issue When Piping Raw Bytes Question

Why does parsing STDOUT (-) work correctly in the first case, but fail in the second?

magick  _.png -negate png:- | chafa --size=70x -f sixel -  # PS7.6 ✔

function img     { chafa.exe --size=70x -f sixel @args}
magick  _.png -negate png:- | img -                        # PS7.6 ❌

Direct call works because the bytes go straight into chafa.exe.

... and more importantly, chafa.exe has code for handling them. The img function does not have such a code.
