Apparently my TV has normalisation, but it doesn’t seem to do much. There is a setting that boosts dialogue, but it’s jarring enough that being the fastest remote in the West still comes out on top.

Maybe I can do something with the spare Pi…

I’ve seen some devices call it “night mode” as well

We need a D.range comic to visualize that

Also make sure settings are 2 channel, if not most dialogue gets sent to a non-existent center speaker. All you’re getting is the “surround” part.
