There is a protector for Samsung Edge, yes. I have yet to see one that fits the curve of the glass. To do so would make it impossible to apply properly due to needing the adhesive coating. It only fits the top part of the screen that isn't curved, and causes readability issues at the edge of the protector.
The same is true for the Lumia 930. YES, they DO make them for the Lumia 930. I have seen them as recently as just a few minutes ago when I did a search to see whether or not they were still offered. I found them on e-Bay, Amazon, and several other sites. It only took a simple Bing search to find them.
The issue here is that you are asking the wrong question, or your question makes a wrong assumption. The Tempered glass does exist for the Lumia 930. The problem with it is that it does not fit over the curved part of the glass which leaves part of it unprotected, just like the protectors fore the Samsung Edge.
