I know he mentions books in the articles but put them away because they either were either too exciting or too boring. To me that sounds like not having tried hard enough. As I said: replacing such nightly habit with another one isn't easy.
I've found success with a formula much more like yours (no blue light for an hour before bed unless absolutely necessary). I understand what he means about books being too exciting or boring too. What I've done is what he does with TV: I reread books (I also lean towards very simple to read books). Just this year I've done Liar's Poker, Moneyball, The Hobbit, and am working my way through the original Bourne series.
