Of course, it's possible, but wouldn't solve your problem: if your image and background happen to have similar parts they will be deleted too:lol: The very same way it happened in your Color Range try.

In general, it's not possible unless you also have the same image on the comletely different background. Then you could restore the actual image values even with semitransperancy.

In your case just put original background on one layer, the image with backrgound on the other with Difference blend mode. Make Threshold adjustment layer with Threshold level 1. Get your mask.

Or you can put both layer in Smart Object and try some stack mode.
