From one angle it looks like a scratch, but from the other a possible grain separation.

What I would do is get a small mirror that you can hold and place it underneath that area via the F-hole.

Then shine a very bright light directly at the suspected area. If you can cover the majority of the F-hole as well, and do this in the dark, I believe you'll see any possible issues.

Most cell phones have a very bright light that you can practically lay against the wood. Spruce allows the light to come through at the typically thicknesses used on solid top guitars.
