Have you tried the embolden text feature, or turning off the flashing refresh feature? I'm very curious to see both.
Anyways, nice vids. It's always interesting to see various opinions. I'm probably the only person, but I actually LIKE that the screen is grey. I usually won't read paperbacks in bright sunlight (without sunglasses) because my eyes are so ridiculously sensitive to light, so I'm hoping the grey will help
