Great looking setup, I love the quest for technical perfection. I know the feeling and am always on the lookout for new ways to improve anything if there is a new thing around the block.
When watching movies in a darkened room you do not see anything else but the movie, so, the slick decoration is not a must if you ask me. You probably only look at it 1% of your time
I never really cared for that part of my home theater until I bought a special projector screen which was just too nice to look at to leave the rest messy
I hope you enjoy your theater as much as you can! In the end, we all make our home theaters to be able to watch movies as good as we can.
