The whole concept of the show is not anywhere near to what you would call bright and rosy!Even the trailer looks dark. Everyone is spending money on 4K UHD panels and the programming looks so dark what's the point? I have a new LG C8 I'll check it out and report back.
Update: Just took a peak UHD version season 3 preview and yeah, it's dark because 90% of the scenes are filmed in a night setting or indoors it looks like.
