And yes the display matters the most to most consumers as that's the primary interface the user has to the phone. A small dim 720p IPS display doesn't cut it anymore in 2024 especially at €400+ price point where Android competition eats it.

What use is fewer SKUs if nobody is buying them?
Nobody in my country(not USA where iPhone is king due to iMessage lock-in and high income) is buying the SE because at that price it's terrible value for money compared to the competition. Everyone is buying mid priced Androids and those with money buy the Pro iPhone but never the SE because it's just shit value.
Apple needs to replace the SE with something more modern with bigger OLED and then it will sell.
