-A ethereum real life example in where this is useful is if you want to update a users balance on every new block so it stays as close to real time as possible. Without using a bloom filter on every new block you would have to force the balances even if that user may not of had any activity within that block. But if you use the logBlooms from the block you can test the bloom filter against the users ethereum address before you do any more slow operations, this will dramatically decrease the amount of calls you do as you will only be doing those extra operations if that ethereum address is within that block (minus the false positives outcome which will be negligible). This will be highly performant for your app.
