    If Unity is using DisplayInformation::LogicalDpi to obtain the DPI value, I think that this may be wrong. I've stumbled upon DisplayInformation::RawPixelsPerViewPixel (only available on WP, not on normal WinRT) and this might be the right one to use. Or RawDpiX and RawDpiY in Microsoft::Phone::Info::DeviceExtendedProperties.
