Lichess opening explorer would probably be a fairly accurate indicator of how the cache hit ratios would develop: https://lichess.org/analysis#explorer https://lichess.org/analysis#explorer I imagine it would look closer to the Lichess database, which differs quite drastically from the Masters database. For instance, with the masters e4 is met with c5 in 46% of games, but on lichess c5 only happens in 19% of games.
