I believe that doctors need physical access to your gallbladder in order to remove it. If that is so they must have had an opportunity to see your liver during your surgery with their eyes as the gallbladder is in very close proximity to the liver. On the other hand the scarred, shrinking & altered texture of a cirrhotic liver can not be missed by a qualified surgeon. I am not a doctor far less a liver specialist. How ever, it is my opinion that the viewing coupled with the negative results of the tests you did, probably is enough to rule out cirrhosis. I don't know if you can somehow have an intelligent estimate of the status of the related bile ducts & other tubes merely by seeing them physically. Nor, I should also say, can you have a definitive decision of the functional health of a liver by only viewing its surfaces, but for the qualified eyes that says a lot.
With those symptoms (though few) you need to take into serious consideration that a part of your gastrointestinal system (not necessarily the liver) had undergone some serious change. Any sudden change needs an urgent & persistent attention until it resolves itself or a diagnosis is reached.
