lol...
so yea mercury filled are fluorescent lamp, most of them are really high temp(7k-8k), which gives the effect of making them brighter than they really are by giving out a blueish tint. You can see the effect by just taking picture of something white(wall) without flash, it'll look blueish for most P&S camera with auto white balance... you could also see the effect by going to any local Home Depot store's lightning section, they have demo there that also show how light effect everything looks.
Your older K3 & new K4 screen will look different under the same light if they have different tint caused by whatever(aging is very likely the cause, notice your old photograph tend to look more brownish? so is your old paperback book? could also be something else though...). But even if it's not due to aging, the change itself does not make one superior to another as long as they're within the same spec(eInk did not specify any color temperature under any observer, only reflectance). It just means that under
your lighting condition, your K3's screen is a better fit(slightly warmer tint vs the cooler one on K4).
Try them both under one of those light, I'm sure you have access to one somewhere, my guess is that your K3 will probably look more brownish to your liking than the K4
