Yes of course there are other ways to identify what is playing but Rose and a few others have designed their streamers to offer this info on the LED screen - good for them.
Some may prefer to use an iPad or other device but I don't often use my iPad and I wouldn’t want to have to recharge it every day so the 1 minute close-down suits.
I'd normally use a Windows PC to start up my day's listening, but of course it gets used for other things too so music info has to be found by a number of mouse clicks. Again, easy enough, but it suits me to glance at the front panel of my streamer. Once you have this feature, you appreciate its usefulness.
All these things add to the convenience of music listening, even though they don’t improve sound quality.
