I honestly still don't get how it's a good idea to have such a frail part being central to the phone experience and we probably don't know what are all the failure modes
For example, I bet Apple is not splitting the video signal and feeding it from both sides, which means that if your screen "fails funny" you get a dead left panel.
Zero-radius folds are rarely a good idea
Folding screens have been a thing for around 6 years now and pretty early on manufacturers realized that 'zero radius' bending was not gonna work, so there were some pretty clever hacks that increased the internal space to allow the screen to fold in a teardrop form to soften the impact.
But regarding the dead left panel, you will have _no_ panel because if the panel fails, all of the inside screen will be affected, since it's one unit.
