Driving myself crazy

In person I can see a vvvvfl it’s pink in color but I can’t get it to show on a pic! Now I don’t know if I’m just seeing a indent or Evap but I saw it after 3 mins

UPDATE: took another test this am, I think the line looks darker but not 100% convinced it’s not a indent! Will take another in 2-3 days and see what happens! Fingers and toes crossed
