Device manufacturers go to a great deal of effort to ensure their devices cannot be identified this way. I'm certain SOME don't have such protection but I would think many do.
Can you say exactly what you can detect with this?
When it comes to smartphones, you are mostly correct.
When it comes to peripherals (earbuds, dashcams, car audio, etc), it's a totally different story. For user convenience these devices happily broadcast useful names, manufacturer data, etc.
