I just did this test and got the first two right: https://www.theverge.com/2017/4/5/15168340/lossless-audio-mu...
The third one was really tricky so I had to guess. But the first two were a really clear difference. Uncompressed kind of sounds "fuller" and sharper, and MP3 is a bit flatter. It's a tiny difference but I think I can hear it.
