I wonder if the small dots are chroma clipping in the channel.
I re-created the animated GIF of the 3 BG images, but instead of display in normal RGB, I did a color transform to YCbCr color space. The reason being, most JPG images are compressed and stored in YCbCr color space. Y is the b/w intensity, Cb and Cr are 'chroma' or color axes that define the color.
I contrast stretched the two chroma (Cb and Cr) images by a factor of 2.5 for better display, but left the Y image along.
ALSO: I have no idea what the small points in the Cb and Cr images are due to . I haven't seen that before that I can recall.
