bq. Shouldn't both replica and leader come to same state after this much long period.
No. After that long, the docs will be the same, all the docs present on one replica will be present and searchable on the other. However, they will be in different segments so the "stats skew" will remain. But displaying the scores isn't a good reason to worry about this. Frankly, that's almost always a mistake. Scores are meaningless outside of ranking the docs _in a single query_. Because a doc in one query got a score of 10 but some other doc in some other query scored 5 doesn't say anything at all about whether one was "twice as good" as another. Even within the same query, the same two scores don't mean one doc is "twice as good". I think this is a waste of effort frankly. At best, I've seen UIs where they display, say, 1 to 5 stars that are just showing the percentile that the particular doc had _relative to the max score of that query_, unrelated to any other query. If you insist (and again I think it's a mistake) you can optimize periodically, but if you're using anything earlier than Solr 7.5 that has its own traps and I do NOT recommend it unless you can do it every time you change your index.
