I bet there might be something but you can probably create your own by using ImageMagick[1] and some manipulations. For ex. for images, I would create a temp file or use a process substitition + open on OSX or xdg-open on Linux. Here is a first post about
Or you can make it even easier(cause the output is only a text) and simply print out the difference in metadata directly. You might need some other tools like ImageMagick but at least no shenanigans with viewing binary data as part of your diff.
I would recommend Node-RED but that's a lot more work than a Zapier or N8n but you can do more with it - Node-RED abstraction level is closer to a programming language than a SaaS combinatorial tool.
Depends on what you want to achieve and how much effort you want to apply.
