I wouldn't worry about that at all. Most drain plugs do not completely drain the oil pan. I've seen as much as a half quart of oil remaining in a pan after dropping it. Toyota seem to be the worst at this.
Fear not, because if your engine has an oil cooler, it's keeping some of its oil anyway. Fear not. Even with my oil coolers (all my vehicles have them) keeping some oil, my UOA's come back excellent,,even when I don't change the filter.
