The thermal discharge indicator is a visual status cue for the fire suppression bottles. When one or more bottles have discharged, the indicator on the aft left fuselage turns green, giving you a clear, at-a-glance confirmation that the extinguishing agent has been released in the protected area. A ruptured indicator disc would imply a different physical indication, not the standard green cue used here. No indication would mean no discharge, and a fault alert would point to a system fault rather than discharge status. So the green indication is the correct sign that discharge has occurred.
