If the branch of physics says energy is observer dependent, no
they are not the same. But then that is why we need different
branches of physics.

Physics isn't very good at answering philosophical questions.
It puts real things on one axis, imaginary things on another
axis and that assures total rejection by any philosopher worth
his salt.
