I have no idea; I know some forumer might be having similar problem, so maybe the AMOLED is really like this, or my unit is more obvious. I need to test out other units when I visit any Nokia Shop, hope they don't ban me, LoL....
Last time I test and compare, both unit set to maximum brightness, it's very clear that mine is different, even capture on camera, still can see the difference. Seeing LIVE is more obvious.
Then at NCC, 1st time send in, they don't have the demo unit, but luckily one customer send in the N8, and we compare side by side, cleary can see the difference.
2nd time send in, they have a demo unit already, so compare again, still can see difference, although their demo unit also can see a little bit.
You should see my phone when playing dark videos, it's crazy awful; Imagine those people wearing like MIB, their black pants and coats will see all these problems.
Check out this TRON video I captured, this is what I'm talking about, having "layers", the light and dark like have separate layer, it didn't blend smoothly. If got smokes/clouds, you'll see multiple layers from black to gray to lighter colour.
