When you say quality it can in fact mean either or both. This would depend
on the manufacture and how much they are willing to put into R&D to produce
a product that meats their exact quality standards (playing around as you
call it). And yes at the high end these formulas are very stringent, so
'exact' is not an unacceptable term to use. They (the OEM's) also tend to
formulate for best results with their paper and of course in their
particular printheads and that is why they often if not always recommend use
of their papers. Of course there is a marketing aspect, but papaer
recommendation is not ALL sales pitch as some would think. Photo papers
containg varying sizes of pores and the ink and droplet size is geared for a
specific type paper. Add to this the various types of coating used on the
glossy paper types and these all will interact diffently with different
inks. Certain inks may cause a magenta hue when used on a particular paper
requiring driver adjustments. Others may cause a cyan hue.

Again, I agree there may be some suitable inks out there for various people
and uses, but the formulas are not exact and that was what my comments were
about. By the way not sure what Canon Ink you are paying that for, but if
that is an honest figure that is more than 200% the cost in the U.S. even
with the exchange rate. I generally pay about $35 for a set on average.
