I had this replacement lift gate glass from an SC for my 2019 model 3. and it came like this. And they said, "it is a normal characteristics of a new vehicle to have these imprints in the glass."
I don't have lines, I do have 4 double circles with 4 dots in each one equally spaced across the hatch glass. 2023 MY LR. Spotted them while sitting in the garage looking in the mirror.
