No only IE sorry :P
I saw this link too, but to be honest Nokia uses displays from 3 different manufacturers in 5530 (or 5800). I saw comparision pictures for 5530 (5800) long time ago.
Dell too uses different manufacturers - LG, LGPhilips, Samsung, AU.
It will be interesting to check what we really have under our tablets.

Note: On the max britness level my N900 is very well.
But on all other britness levels its appear too dark for me.
It sometimes represnts white color more like yellow,beige, warm white color.
Based on my experience It smells to me like Samsung display.
