Would indent line show up on invert as glowing?

I swear there was a line there- on an answer brand- so after documenting test together, I opened it up- to me it looks colorless but the invert isn't glowing "black" in the indent area like my bfn tests this one is definitely glowing like the control line- I'll post pic of negative invert indent line and this one- I'm not going to test again for a few days and know this test is invalid just want personal experiences with this..
