I have removed and replaced carpet on my boat. The front deck is not the same quality finish as the outside of the boat. In other words, you can see small squarese that are made by the supporting underlayment. It isn't bad looking but just different. The glue is very difficult to remove completely so that you have a totally consistent color pattern. The best I have seen is when a gentleman used xylene to remove the old glue. His removal of the glue was the best I've seen. Of course, you then have the issue of the five deck lids being made from aluminum. On my boat, the factory had machine sanded the finish off the lids to get the glue to stick better. That won't look nice without some enhancement.
