I don't have the details of the aging test, so don't know if it continuously on. It could get switched off once a day off once an hour to simulate actual device usage of heat up and cool down.
A continuous thermal aging test is really about increasing the rate of thermal degradation of the material. So pausing the test and allowing the material to return to normal temperature for a period of time does not necessarily mean the test has to be rerun from time 0. The material degradation after 2000 hours does not "recover" when the test is paused. Simply restart the test and run for another 1000 hours and you have a complete test with 3000 hours of thermal degradation.
Continuous non-stop testing would only be critical if the application had to be non-stop, like a heart pace maker. For displays and lighting, these are actually typically off and on applications.
A single pause is not a big deal.
