If they were active (ie: they shoot IR at a target and wait for it to bounce back and hit a receiver), then bending IR would matter.
Bending IR absolutely matters. The IR is radiating from the heat source. The heat source is beneath the blanket. The IR refracts back towards the heat source when it hits the blanket. The IR never reaches the scope.
If the blanket isn't thermally insulated, then the heat source may heat the blanket and cause it to radiate as well. That would obviously be visible to the scope. But that's an easy problem to fix.
