It changes screen to screen. on my macbook pro screen f.lux produces some mellow golden (?) tint to the screen and basically unnoticeable, but I have a cheap samsung 21 monitor, and on that f.lux makes screen quality deteirorate noticeably. Think of it like that: your lcd is certified to have a certain color gamut at 6800 kelvins. (daylight) But when you push it down to 3000K, there is no guarantee that your lcd will retain same color range - and in most cases it doesn't. That's probably why its about quality of your lcd. Most budget laptops has pretty bad lcd's, so it makes sense that your laptop doesn't fare as well.
