Depends on the junction drop. If you have two LEDs perfectly matched, say 1.75V ea (or thereabouts) - both will share equal current. Tolerance levels are considerably quite remarkable nowadays. No need to spend hours with your meter looking for matched BJT pairs for that destined to be perfect amplifier.
