A sequence of 40 zeros is highly compressible, but does not look random.
You mean a sequence “looks random” if it’s not very compressible—right? That is, the sequence is a member of the appropriate typical set:

Or maybe you meant “looks random” means “compressed already.” (???) A zipped file expressed as a bit sequence looks random.
I’m sorry, I meant to say that randomness is not compressible.
