Android :: Media Insert Image Locked To Heavy Compression

So from what I can tell Media.insert Image is locked to heavy compression on all images. This includes when passing in the path to a photo in the filesystem. As a test I used a 3000x2000 pixel jpg which had been previously saved at maximum quality and was ~6MB. After passing the path to Media.insert Image, the resultant copy (still 3000x2000) is 623KB. I passed in another copy of the 3000x2000 image, this one compressed down to 393KB. After Media.insert Image, the image filesize is 492KB. I'm wondering if there's a way to specify the compression when images are saved by insert Image. I'm also wondering why this is recompressing jpgs, rather than simply copying them into DCIM. A side-effect of opening and re-compressing these images is that it imposes a rather low VM cap on what insert Image can handle. I'm getting out-of-memory errors when trying to pass the path of a 10 megapixel image.
