I would have said true, only because -- not having been privy to your lectures -- I would assume less of the surrounding scene would be a different prospective. AA said, his purpose was to offer a sense of presence, which included the ground within the surrounding scene. While this 'prospective' is aesthetic, it would be my assumption that the longer lens would change the perspective. If your question is to test the understanding about DOF and paralex as understanding perspective, you might be more specific about what you mean by 'perspective.' As the circle of illumination remains consistant with lens changes perspective remains the same. T or F S.
