Hello I have a question for people with more experience in LCD separation. Look at the picture in the second link below - there are several marks on a display of an iPhone 6 I have not encountered before, red line and dark spot. The display was broken after a fall. Here is a picture before separation:

According to the technician words, the dark spot on the bottom right side marks a place when the display is a bit bent - which was not visible with the glass glued on top of the display. Thank you in advance

Vertical red line looks like it is on the polariser film you have fitted (they have protective films you remove), along with the black/grey circles. The dark smear in the bottom right is probably where liquid has leaked into the backlight (when you were cleaning the glue), but it is difficult to tell from picture.
