Doubt it... A plastic screen is more durable than glass hence why Nintendo used it. It is the primary reason why many "shatter proof" phones use plastic screens. The downside is of course, plastic will get scratched more easily. Dead pixels is nothing new and a small % of every handhelds and pretty much any screens have them.
The joycon rails are the only hmm thing cause its not the rails themselves thats the issue but how they are attached to the unit. But even then, unless you are purposely trying to break it, I doubt it will get damaged.
