LSB Bit-Plane

i have used "bitget(Image,1)" to retrieve the LSB bit-plane for two 512x512 different gray images with the same size. I noticed that one image gave LSB Bit-Plane as complete noise (left image). But the other image its LSB Bit-Planes had information about the original image (right image). what is the reason that the LSB Bit-Plane of the other image is not a complete noise like the first image?

Could be lots of reason. Maybe one image is just noisier than the other one. Maybe one image is saturated/clipped. Maybe one image was just quantized or smoothed or enhanced.
