Vvvvfl or not? I think I have line eyes!

The bottom one was taken yesterday (10dpo) with Superdrug early response test, and the top one was taken today (11dpo) with a boots early response test. The bottom Superdrug one looks like it might have a vvvvfl but I don't know if it's real or just my imagination. I know the superdrug ones are supposed to be super sensitive. What do you think? I've also tweaked them to see if that helps!
