Do CCFLs lose whiteness over time?

yes they dim as they age. for critical color work, calibrate periodically.
CCFL screens become reddish over time. LEDs turn cyan, but as far as I know their color drift occurs much more slowly than CCFL.
But when you say "sandy-whites" I think you might be referring to something different. The anti-glare treatment on displays can create that dirty, or sandy, look. This is what gave older IPS screens the reputation for having a "screendoor effect", as it was hard to find any that didn't have heavy anti-glare treatments. These days manufacturers seem aware that heavy anti-glare treatment will ruin the perceived image, because like you noticed it's impossible to produce the appearance of pure colors with heavy anti-glare.
