I fear your issue is not unique to the M series model All laptops have a physical weakness!
The Display is a plate of glass and just like a window pane it doesn’t take much for it to be damaged! The risk is people forget they have a book or some hard object sitting on the lid pressing down and when something or someone sits directly on the system or the on the bag which has both objects the display gets damaged.
I would say about a third of the display issues I’ve seen can be traced to compression damage or physical bang/drop breaking the fragile electrical traces within the panel, requiring the replacement of the display assembly.

Some pictures may be helpful. The repair center didn't offer any feedback, but are they fixing the issue?
