Hi,
I'm not able to understand what is what in your screenshot.
But please consider that during the upload of an image, the thumbnail is generated by the javascript with the full image while the product images are just thumbnails.
If you're using a device with a retina screen ; the "blurry" effect is just the result of retina processing.
