I've made a post looking at what changed about Shenhua's house in S3 compared to S2 - the obvious one being the extra room, as well as the smaller details of what objects have been removed or changed between the two games. Overall I don't think the changes have had any material effect on the game's story (although the removal of the tapestry might hint at a reduced role for the city depicted).
Also - the loom model found on the mat area in Shenmue 2 is actually impressively intricate when viewed up close, compared to the gloomy half-covered view you get in the game!
