This is a garbage analysis. They estimate the display to cost $65. We know that is wrong, as KGI (who is essentially perfect) estimates it at $120 - $130. Given the quality of the display, I would lean toward KGI being correct - we should disregard TechInsights entire analysis.
That is not how it works. $130 is the retail retail price, Apple is sure as hell not paying that much for a screen. Apple buys those screens by millions at manufacturing cost. KGI were also the ones who said Apple will have a problem with X production and never meet the demand in this year, which is clearly false as we saw not only improvement in shipments but also 3-4 weeks order wait time.
