The command is working as designed, either for newly added ones,
modified ones, or deleted ones.  In your sample output, we can see
"Binary files differ", which is the default "diff" for binary
contents.  It is in line with the way "diff" by other people work.

As the primary purpose of "git format-patch" is to convey the
content change between pair of states (i.e. change to bring the
state at a particular commit to another state at a commit that is
its child), it implicitly enables the "binary patch" option, but for
"git diff" which is meant to be an interactive browser of changes
for human consumption, the "binary patch" option is off by default.

You can run "git diff --binary".
