Yes, cold cranking is 100% port, once it catches and fires up into high idle mode it is dual fuel (port and direct). Once it idles down and the load drops but before it is fully warmed up (switched to direct only idle once fully up to temp) it is port only at idle.
That logic follows the normal injection ratio tables, once you are out of retarded timing idle mode the DI firing angle follows the GDI tables (all 3 look like the attached):
