Actually, I don't know that. I'm not a Mac user, yet.
The Retina and TrueTrone LCDs are supplied by LG.
While LG have supplied displays to the market (and to Apple) for decades (and Apple, since at least 1999, but likely further back into the early PowerBook G3 days of 1996), Apple arranged, at the time the first retina displays for laptops were coming out, that LG be their exclusive supplier and, after a point (circa 2016, as memory serves) and that LG may not sell the retina LCDs to third-party vendors/distributors under any circumstance.
What this meant for the Apple realm is there are no parts available on the reseller market for replacing a failed/broken Retina LCD unless one goes to Apple exclusively. Which may be fine for a few consumers, but once Apple designates a Retina-equipped Mac as “
obsolete” (it’s quite a list), there is no redress for repairing/replacing a failed/broken Retina display, short of cannibalizing another identical product (i.e., cannibalizing a 13-inch early 2015 MBP’s Retina display with a dead logic board, for your own early 2015 with the dead display).
Worse, sometime after Apple added the T2 security chip to all their Macs (for MBPs, this began with the Touchbar series of 2016), they began to use a method of cryptographic matching/mating/“pairing” of components within a Mac to only work on that Mac (a technology borrowed from iPhones and iPads). Which means, in a practical sense, were one to do a display swap similar to my 2015 example above, but with one of these newer models, the system may disable, say, the iSight camera on the replacement display, even though there’s nothing incompatible or amiss about its genuine provenance.
In effect, these moves by Apple can and do accelerate the cycle of sending otherwise fully functional products to the crusher years too early and out of end-users’ hands. Call them “disposable appliances”. It wipes out the secondhand uses market and incorporates the above-described methods to thwart upgrades, repairs,
or even component replacements (note: link demonstrates this with iPhone 12, but the same function is now carried over to Macs).
Once more, this is what a company can do when they approach becoming a monopoly.
The above are considerations one ought to evaluate when looking at or shopping for a current Mac — especially so a laptop.
