영속성 컨텍스트와 LAZY 로딩 관계

안녕하세요. 영한님
강의를 듣고 궁금한점이 있어서 질문드립니다.
영속성 컨텍스트와 Proxy, LAZY 강의를 들었을 때 Member 엔티티안에 Team 엔티티를 필드로 가지고 있고, LAZY로 연관관계를 설정하였을 때 , Member만 조회하였을 때는 Team은 아직까지 Proxy객체에 null로 있고, Team의 데이터를 조회했을 때 Proxy객체가 Team 객체를 참조하는걸로 이해했습니다. 그렇다면 Team의 객체가 null로 초기화 되어있다가 조회한 데이터로 초기화되는걸로 이해했습니다. 아니면 그냥 Select 쿼리만 나오고 Team proxy객체는 계속해서 null이고 Team 데이터를 조회 할 때만 select쿼리만 호출되는걸까요..?

List<FMSCompany> contents = companies.getContent();
for (int i = 0; i < contents.size(); i++)
        {
            FMSCompany company = contents.get(i);
            FMSBranch branch = company.getBranches().stream().filter(fmsBranch -> Objects.equals(fmsBranch.getId(), company.getHqBranchId())).findFirst().get();
            System.out.println(branch.getLocation() +", "+ branch.getCompany().getId() +", "+ branch.getBusinessRegistrationNumber() );
        }

}

FMSBranch의 데이터를 조회를 했음에도 불구하고 FMSBranch Proxy는 계속해서 null로 초기화 되어있습니다..
