If we're being all technical here, the title might still be true based on the number of Bitcoins lost in the ways you describe:
Certainly lost forever are those sent in OP_RETURN scripts, unclaimed miner's rewards, and coins sent to nowhere such as transaction - "5bd88ab32b50e4a691dcfd1fff9396f512e003d7275bb5c1b816ab071beca5ba".
I see there are 100 bitcoins lost in that single transaction. No idea how to get all of them though.
You can't. There's no unlocking script that can unlock that output. They're sent to a locking script that's invalid.

I mean a way to get a list of all the transactions that are like that("sent in OP_RETURN scripts, unclaimed miner's rewards, and coins sent to nowhere"), them sum them all up and see if they're less than 3,034 BTC.
Until that's done the title still might be true after all :)
