Thanks for the links, much appreciated. I knew about non-coding or junk DNA but had forgotten how extreme it was. Ended up learning about the onion test[1] and this interesting article[2] which suggests classifying non-coding DNA as either junk DNA, spam DNA or both, to better capture the differences that exist. I also found this article[3] providing some interesting overview and discussion on the topic.
