You're probably right. But the shift is also very visible just between 
the two lamps on my desk. Under one lamp a deep blue sky will look way 
too purple, under another it's closer to what I see one screen. If I 
move closer to the window it starts to look cyan.

Once I swapped out the yellow cartridge with an UT yellow (very light 
carbon gray) cartridge to see what happened when I printed a grayscale 
image. The resulting image was bright purple, which means they Epson 
driver is running all the colors nearly full strength and trying to 
balance them out to look neutral. Very different from the IP/QTR 
approach of printing mostly K+LK and subtly toning them with just enough 
ink to make the print look neutral.
