Here's the same picture for comparison on the two devices. It took about 20 tries. Hard to take it in focus and not have glare. I'm no photographer, that's for sure.
It's high res. Feel free to download it. I suspect the site where I posted it will take it down.

The screen protectors were off both devices.
Both devices were turned up to maximum brightness.
My impression is the 4705 looks marginally better, but it's a minimal difference, and I am biased.
Will update on battery as soon as I can.
Hope this helps.
