Remember that the very first DVDs were single-layer, and even they had to be flipped in many cases to play an entire SD movie at an acceptable quality level.
I actually do remember that. I had a few of those being a fairly early adopter('98)(also a very early customer of Netflix). No artwork on the disk, just a little band near the hub that had the title and if it was the A side or B side.
