Better image quality for device/web preview
The quality of @x1 images when previewed on iPhone or web is very poor when the image is long, e.g. a screengrab of a long web page.
Images imported look fine on preview but really blurred when the prototype is shared. Can't present the prototype to a client like this.

This is to do with the placed image's size, not necessary to do with the retina display upscaling. For example, if you place a very long webpage screen-capture in an artboard, the image quality in the desktop preview is good, but when you publish for the web preview, the quality is so poor that is well beyond acceptable level (cannot read any text due to bad pixelation, for example) This is very easy to replicate.
