Long story short I had three different s24u devices to check the displays, all devices showed this weird film grain defect.
1 pre order, release date device. Vietnam.
1 samsung exclusive colour (Feb) made in Vietnam.
1 new stock, gray, (Feb) made in Korea
Last device made in Korea was newly brought in stock for the UK.
All three devices had this oled mura grain,
I'm assuming that Samsung has just decided to cut corners on their displays.
I have a couple of colleagues that also have the s24u and will ask them if I can check their displays.
So far seems most units have this, I don't know if people who claim that they don't have this issue actually know what mura looks like.
Anyways food for thought.
