The problem is a defective screen that will need to be serviced at the Apple Store / Genius Bar or an authorized Apple service shop.

Welcome and thank you for reaching out. 🤗
There appears to be a problem with the internal display panel. Only a certified Apple technician can determine the cause and offer a complete solution.
Therefore, I recommend service.

A screenshot captures the digital image generated and rendered by the device’s operating system and apps. It does not capture the physical condition of the display panel itself.
In simple terms, a screenshot records what the device is sending to the display, not how the physical display is actually reproducing it.
Therefore, screenshots bypass physical display defects such as:
A green or pink line caused by a defective OLED/LCD panel is never part of the screenshot. The line is introduced by the physical display hardware while converting the digital image into something visible on the screen. Since the screenshot is taken before that physical display stage, the defective line cannot be included in the screenshot.
This provides a useful diagnostic distinction:
If the line appears on the physical screen but disappears when you take a screenshot and view that screenshot on another device, the problem is almost certainly with the display hardware or its associated circuitry—not with the image being generated by the operating system.
Conversely, if the line also appears inside the screenshot, the problem is more likely to originate earlier in the graphics/rendering pipeline—for example, the software, GPU rendering, or the content itself.
So, a screenshot should be understood as a digital representation of the rendered image, not a photograph or diagnostic record of the physical display.
In short:
A screenshot captures the pixels the device is generating; it does not capture defects in the physical pixels of the display panel. A green or pink line caused by a display-panel failure therefore cannot be part of a normal screenshot.
