From my experience with game engines and people that really care about CRTs - I believe the effect (confidence: 95%) can be entirely achieved with rendering glue in any of the modern game engines - Unreal, Unity, Godot, etc. Now, whether or not it is a literal shader, or a shader + custom sauce, not sure.
However, I have not tried, so I cannot verify that claim to 100% accuracy. The author ...might have tried? They definitely surveyed the landscape. My read of the article was that they went down this rabbit hole and back-justified it instead of investing a similar amount of time in a practical solution in a modern engine.
CRT look and feel is a niche full of very passionate and opinionated people.
