I was able to add it as a "Color Filters" "quick control" toggle from the top right drag-down menu (not sure what you call that) in iOS 17. We'll see how long I last with it. I'm intrigued as well.
that menu is control center
I keep it in my control panel so I can flip it on and off easily
I ser the Accessibility Shortcut to Color Filter. A triple press of the button toggle the filter.
