You are correct. I have a 75 watt CO2 laser and can't do bare metal, but you can easily do coated metal and burn through the coating.
You have to have a fiber laser to burn or cut bare metal.
You can burn the coated stainless Yeti cups and stuff like that too. They turn out really nice.
There's also some paint stuff you can spray on bare metal and actually melt it onto the metal and then the non burned area just washes away. Very durable way to print graphics on a bare metal surface.
Here's an example of cups we did for the grandkids.
