I'd expect there's some lost scale opportunities. Outside of the really unique designs (folding, etc.), most phone screens tend to fall into a few basic size classes, but we still end up with wildly varying designs within those classes. The connectors are different, it's 2mm larger or smaller, etc. I suspect when a manufacturer orders 100,000 the engineering costs to make it a little custom are insignificant on a per-screen basis. If we had more top-down economic planning, there would likely be a single Display Monopoly, and they would say "here's the one six-inch display model for 2023". Whether it went into a Samsung or a Umidigi, there would just be one replacement SKU, and it would be far more feasible for repair vendors to stock it. I busted my Lumia 1020 back in the day, and ended up retiring it because local repair shops were all 'weeks, if we can get the parts". If you had an iPhone or certain Galaxy S models, you at least had some chance spares were available from parts phones. This would mean that even if you had something other than an iPhone or a recent Galaxy S, you'd have a chance of an affordable replacement part.
