If you have a " completely light-controlled theater ", a white screen with a gain of unity - 1.3 max is the way to go in my opinion. I think you are still good with your current screen.Bummer that Carada Flopped! I loved their CS...I had a custom 2.40:1 115" BW screen made for me, about 4-5 years ago. I still use it in my current theater! I'm just wondering if going to a dark energy screen, or other ambient-rejecting screens would even benefit in my completely light-controlled theater. hmmm...But I do love the texture (or lack of texture) from the brilliant white material....very smooth, and pretty much was 4K ready, years ago imho.
