I am inspecting the prints under a GTI Soft V, so I guess the cast is not metamerism.
Can anyone assist ?
Well metamerism in a pure sense involves two samples of similar nature. Your screen to print even if in a viewing booth is not a metameric matched pair.
The paper you use may have high amounts of optical brightener which will cause a colour cast in fluorescent lighting regardless of white point and CRI.
Do you see a huge cast in tungsten light? Daylight? That will tell you if the profile is creating the cast or if it’s simply illuminant metamerism. Try taking a classic print and compare them both in different lights to see what degree of failure the Canon print has.
I actually edit B&W profiles in PE for a closer match for composite printing and get very close to neutral. The screen previews though even when editing do not match as much as I have tried.
For that you need to edit the rgb to Lab table in the profile , not the Lab PCS to rgb tables which would change the output on the printer side.
