Salvage VS Exploration Salvage

I am on my way back in from about 1000LY out exploration run and at about 300 LY out I started seeing DEGRADED Signals and the FSS returns them as SALVAGE or EXPLORATION SALVAGE.
The FSS gives them different signals but so far I haven't found a difference between the few I have investigated.

Are these things actually worth the time??
