Depends where you draw the line. There is not a single non-free blob in the OS that runs there once the bootloader is up (unless you put some there by yourself, which you're of course free to do).
I think you misunderstand what the Purism Firmware Jail is. I don't blame you though. They seem to make it purposefully misleading. It doesn't isolate what runs in the OS. It just isolates the OS updates from the non-free blob updates. The OS still runs the non-free blobs. It just loads it from separate flash.
