Is this likely repairable by reseating/replacing the cable OR ..?

History note: My mid-2015 15” Retina Macbook Pro started displaying these very thin horizontal lines from the top to the bottom and, while annoying in certain lighting, contrast and application circumstances, the ‘thatch’-like pattern did not cause much problem.

The laptop is now displaying waves of colors across the screen - either vertically down the center or horizontally throughout the whole screen - along with a periodic lack of refresh.

A YouTube video demonstrating this issue is located here:

Has anyone seen something like this and, if they have, is this repairable through reseating the display cable onto the motherboard or do I need to purchase a new display (or, for that matter, a new laptop)? I ask because I’d rather someone who’s experienced this before can prevent me from ripping into the guts if I am going to need a new laptop anyway.

Thank you in advance!
