On https://forums.macrumors.com/threads/iphone-6-plus-wallpaper-dimensions.1775299/page-2#post-20540750, it is 1398 x 2592 for Parallax supported resolution in Portrait mode for iPhone 6 Plus.
Accroding to https://forums.macrumors.com/threads/official-iphone-6-and-6-parallax-wallpaper-dimensions.1817236/, it is 2706 x 2706 for iPhone 6+ in both Portrait and Landscape mode.
The http://iosres.com/ says it is 2662x2662.
And iOS 11 wallpaper from https://ios.gadgethacks.com/how-to/get-ios-11s-new-wallpapers-any-phone-0177950/ is 2706x2706.
I notice the padding in Portrait mode is not the same between top and left, the left padding seems about 1/2 of the top padding.
Since the reslution of iPhone6+ is 1242 x 2208,
what is the correct padding of Parallax Wallpaper in Portrait mode ?
