Is this an issue that is repairable by replacing the display?

Hi everyone, as you can see in the images attached, I am having an issue with the display on my MacBook Pro A1706. The issue is that if the display has been left turned off for about an hour (or more), it becomes in a state where only the menu bar at the top of the display is visible. Within 5 minutes, this corrects itself, going from only the top menu bar being visible, to slightly lower down on the display being visible, but having alternate lines darker and lighter and glitching out a bit, to the whole display being alternating lines glitching out, and then within 1 minute of these glitches, the display becomes completely fine, like it should be. I am quite sure that this is a faulty display, but can anyone confirm before I spend £200 on a new display? I am also wondering if this could be the flex gate issue that is quite common on these models. There are stress marks on the back of the display assembly around where the hinges are that make it look like it may have been bent too far back at some point. I am not sure as I bought this off eBay as faulty.

Thanks, Philip.
