When I look at the backplate there seems to be no signs of damage except for a bit of rust one some parts. There's no display at all.The repairability is heavily dependent on what failed, where, how and how badly.
If you look at iPad Rehab and Rossmann channels on YT, those guys can repair some quite heavily damaged boards as long as the failure isn't 12V/16V/20V/52V going to CPU/GPU/etc.
