You are wrong, recovery image is not different and modified time of system image is not different either.

I don't need to decompress each image, enter each directory and compare each file to check if images are different.

Why you want them to be different ?

As you can see only cust.img.ext4 has changed.

The change is irrelevant since only the channel name has changed ("austrulia" as already said a couple of post above).
