Well...Just as I posted this comment I found the solution. They indeed updated this and now the correct installation location is: GTA V\mods\update\update.rpf\x64\data\cdimages\scaleform_generic.rpf\
That path doesn't seem to work anymore. Tried billion times exactly like it should be installed, but nothing changes. Seemingly somethings with this has been changed by devs.
