in Scene DNA is available in scene.display New DNA Struct DisplayData
Added RNA (scene.display).
We already have scene.display_settings which contains non viewpoert

Patch should be in line with the ideas that @Brecht Van Lommel (brecht) wrote in T55008.
As I am not in detail aware of the decisions that have been made for the override feature I want a short review if it is in line with the plans.
