I think those Philips CRTs actually have the convergence magnets INSIDE the electron gun. They are adjusted by magnetizing them precisely when the CRT is manufactured. How many wires go to the coil on the neck? If it's only 2, it's for scan velocity modulation (edge enhancement).

It does have only 2 wires, but I don't think this is SVM; if you disconnect this coil, purity and convergence goes way off. The drive for it comes from the small circuit board mounted on the yoke. I don't see any connection to video for SVM.
Now I've got to go find out exactly how
does it works.
