It really is dealer dependent. The white grease used on the door jambs and rails is probably a white lithium or white silicone grease made specifically for hinges. The darker grease used on your trunk struts is likely a heavy bearing grease. They may have applied the same grease to your hood struts as well. Again, this is all at the descretion of the dealer, as they have have lubricated more items, or just what you see. They may also have used a variety of greases.
