Not sure I understand.

Radiation energy decreases due to the universal
expansion and related red/black shifting, 
dark energy would increase due to expansion ....

It is supposed that total energy (radiation,
matter, dark energy, + gravitational field energy)
is conserved (by definition, I would say).
