It may be, but it seems to be an assumption without verification. The
reason a great deal, if not all, yellow is removed from the various UC
monochrome solutions out there (like IP) is that the light K ink now
running all the way up the scale is very warm, and no yellow ink is
required. Actually, to help metamerism as much color ink as possible
is removed with these solutions, but some CM (or light CM) is required
to neutralize the warm light K.
Someone toying with QTR and UCs could test and confirm if the presence
of yellow ink increases metamerism.

You may be giving Epson too much credit, I doubt much technical logic
went into whatever decisions led to these results.
I think Ernst is correct, that the inks just happened to perform best
under tungsten, then they responded to user complaints with the new
driver.
Users are so pesky, looking at their prints under various light sources.
Regarding profiling for different illumination color temperatures,
it's pretty common these days. Particularly for work for specific
installations or exhibits. Still given the lack of sophistication with
Epson's pre-Atkeson profiling, I doubt they were doing that.
