1st - if you don't see it - don't look for it to be able sleep well
you'll need output solid and grey color one by one to the TV
Some see it better for blue and some for gray
Look from 30 to 45 angle this will amplify (magnify) banding issue
The real issue is that when you saw it on your TV it imprints in your memory and for any watching you'll see as static overlap on top of picture - like a dirty window
My description is only to give you hints.
The real bandings is different vs what people talk about - it's limit of TV to produce gradient colors - you see strict separation between half tones.
