I have a sneaking suspicion that the older monitor is the cause of some mild yet persistent headaches I've been getting recently (though I think I'll get a cheap carbon monoxide detector as well to make sure the main one is working properly), I couldn't help but think that something about the display has changed recently, but I can't put my finger on it.

CFL backlight and LED backlight both have the ability to be great or to be sh*t. Ultimately if you don't calibrate your monitors to the same white point, it's hard to say what the actual culprit is. All displays get dimmer with age, which is why you should recalibrate ever so often. Generally speaking, you have to account for this:
