-`list` and `get` will omit binary data whenever it's a human reading it. If it's being piped somewhere or ran outside of a TTY, it'll output the whole data.
+`list` and `get` will show a summary for binary data on a TTY. If it's being piped somewhere or ran outside of a TTY, it'll output the raw bytes.
 
-`include-binary` to show the full binary data regardless.
+`--base64`/`-b` to view binary data as base64 on a TTY.
