Two EVOs-One a Nova and the other Epson-My Findings

I posted this over at XDA, but thought it was worth sharing my findings here;
I just received my other EVO the other day and was wondering why there were such great differences between the two displays. I found that the one I've had for months is a Novateck and the new one is an Epson. The Nova is HW rev 02 where the Epson is HW rev 03. Both are rooted running the same latest Netarsky Kernel and OMJs latest ROM.
1) Confirmed that the Nova panel transitions smoothly between brightness levels where the Epson is instant.
2) Both have the same amount of poor transitional latency between mid-tones(grays) and whites/backs. Both have the same excellent transitional latency between whites and blacks (nice for scrolling text).
3) Viewing angels is exact between the panels. Both fade yellows to white at any viewing angle grater than 30 deg.
4) The Novatech panel has far greater apparent dynamic range whereas the Epson seems flat with a yellowish tint to it. The Nova has a slight but pleasant bluish hue cast with just the slightest hint of magenta. Empirically the Nova seems to 'pop' with more vibrant colors than the Epson.
5) Both EVOs score comparatively using Quadrant, LinPack, and FPS2D.
6) This is not releated, but worthy of a note; The New rev 03 EVO has a much better camera than the rev 02 EVO. The rev 03 EVO has much less noise and performs far better in low light. The differences are remarkable.
