When you say "bluish", how much ? A little ? A lot ?
If it's a lot, then there is some problem with your workflow.
Why are you using the -f flag ? It's not something that you would
normally use when getting your workflow sorted out.
If you are worried that FWA/OBE is a problem due to a mismatch
between the instrument illuminant and your viewing illuminant,
then better to match conditions initially (i.e. view your prints
under incandescent) or use a FWA/OBW free paper to establish something
that works.
Gross problems are typically caused by gross errors. i.e. a patch
numbering mismatch, a mismatch between test chart printing color
handling and the color handling when actually using the profile, etc.
The former typically generates large self check/fitting delta E's.
The latter can be diagnosed by manually converting an evaluation
chart using cctiff with the source space and device profiles and
print it out using the test chart print workflow.
To improve the profile I created a printer linearization calibration file from the initial
729 .ti3 test chart patch values.
Not really advisable until you get your profiling figured out. If something is
wrong,
adding another complex step just makes debugging harder.
