Most DAB radios I find¹ have text-only displays. Some even have no display at all and you must tune in blindly with arrow buttons. Apparently color graphical LCDs increase the cost of the radio enough to omit them from the design.

And yet at the same time people are throwing away quite functional smartphones in mass quantity (thanks to capitalism and designed obsolscence).

Also note that (most?) DAB radios have a USB port for attaching a drive holding music.

Wouldn’t it be sensible to create a DAB radio with no display, but with the possibility to connect a smartphone which runs an app to show station metadata? (Would also be useful if it could connect to the LAN to feed metadata and even accept commands, but that’s another discussion)

I also suspect existing radios could be hacked. That is, radio flashed to decode the signal metadata and (for ease) write it to USB mass storage, which a smartphone can mimick while running an app to display the data that lands on the SD card. The problem would be phones refuse to simultaneously mount external storage that is externally mounted. Could a rooted phone read-only mount an SD partition that is externally mounted? Perhaps the mass storage hack is a broken idea, in which case we would need to invent a protocol for this. Or does a suitable protocol exist?
