Apple Signs Two-Year Deal With Samsung For 92 Million OLED iPhone Panels

I don't know any other manufacturer of products that has "this Issue". The issue being having 30 to 40 million units of products being available at launch and then expect a steady stream of slower sales for the next year. Manufacturing just does not work this way, especially since it takes some time to ramp up and iron out the bugs, which is why there seems to be more product issues at launch.
LCD uses backlights to illuminate pixels while OLED uses Light-Emitting-Diode which enables each pixels to light up themselves. You can view LCD as a subtractive and OLED as additive. Sometimes LCD is called transmissive and OLED emissive. The concept should be easy to understand for most folks.
Burn-in on OLED is caused by uneven wear of the pixels (diodes). It has been known that blue diodes do not have as long a life expectancy as red and green diodes. This is why Samsung uses Pentile matrix for their AMOLED panels and always tweak the shapes of sub-pixels and the distances between them, etc. Presumably they are trying to find the best combination of sub-pixel arrangement to accommodate other technical advances. (e.g. improving brightness and power efficiency)
The pros and cons of OLED (v. LCD) have been debated to death. LCD has generally provided higher peak brightness (although this seems to be changing), is more resistant to burn-ins, and is more power-efficient in today's web environment where white backgrounds dominate. OLED's advantage comes mostly from its lack of backlights, which in theory and practice provides infinite contrast. This means OLED does not need to match LCD's brightness for comparable legibility in a given environment, while its true black offers visual fidelity that cannot be matched by even the most advanced LCD technology. Another advantage of OLED is that it can be "printed" on pretty much any surface because it does not require backlight, and this makes curved display possible for smartphones.
Burn-in is an issue for any display technology, but it is particularly acute for AMOLED due to the way tech works. The question is a matter of degree, and what kind of tolerance level Apple will set for its products. It is about balancing the benefit and cost, then finding the optimal middle ground.

True, but it *can* happen to any one... The fact ts only Apple doesn't not mean they are in the spotlight as "well why is Apple having trouble" as it may not be Apple's fault... it could be the suppliers, or constraints put on them by Apple,, "We need this done in this time frame" could be most likely as well.
I'm not gonna say it can be, but you never know whats possible.
