13-inch 2017 Macbook Pro backlight bleed

I have a 13-inch 2017 Macbook Pro (non touch bar) with two thunderbolt 3 ports. Around a year ago I had the entire screen/case replaced at an Apple authorized repair center. Now, there's a small backlight bleed on the left lower corner. A year seems like too short of a time for the screen to be malfunctioning again so I'm wondering why this might be happening. There have been no drops or other physical traumas to the screen.

I did have my laptop repaired as a part of the solid-state drive service program, the keyboard program, and I had my battery replaced within the last year. If that's relevant at all, I don't know.
