Any filtering scheme is still subject to fade, particularly the blue because it's nearly impossible to to filter out UV light from the source, even LED lighting. Plasma, LCD TVs, LCD projectors (particularly) show evidence of yellowing as they age...

My old Sony 40" CCFL, I just checked, 65,535 hours since 2008 when I bought it. Has never been serviced. Only issue is the blue that I may eventually have to replace it for. It is apparently fading and I think you just confirmed what I've been seeing. I have to run the red and green all the way down to get close to a gray scale now.
