I've been doing the Samsung shops. Much easier to do. No instore photo of the display. I've done about 15 in the first two months. New condition: shops require owning an Apple, Samsung or Other android to perform it. I have a Pixel and S10e, so I do two of the three shops.
Do not read so much, look about you and think of what you see there.
