The profile package and the measuring instrument are together in this.
Given the basic prerequisites, such as printer repeatability and
standardized viewing conditions, technology is still not perfect:
1) most instruments are confused by the "over100%" reflectance -at different
wavelenghts- returned by fluorescent inks and papers. Some just don't read
over a certain reflectance. Sensor saturation? electronic clipping? who
knows, the fact is it happens.
2) using a discrete, and relatively -to the color space covered- small,
number of patches, the profiling app might not catch a quirk caused by a
quirky printer driver at a certain point. Not only crossovers in gray, but
also inverted ramps, etc.
Not to mention all the subjective and endlessly debatable things, such as
"how average the standard observer is?" and "my blue is not your blue".
So given the imperfect technology as (1) and (2), yes, profiles usually need
manual tuning if you want the absolute best match.
And as Johan said, from then on you can go doing great prints time after
time... And with a good profiling package and/or rip, linearization is all
it'll take to keep them accurate over time.
