That's not the full haul from the 23 chests but it's nearly the lot.
As you can see, it's probably not worth it to buy keys for chests at the moment. You could buy these materials at a much better rate directly. Even with this secondary method of gaining items and another chance at a weapon skin the chests feel a bit disappointing. Hopefully it doesn't change our gem > gold holiday even flipping strategy.
If you are like me and experimented with the chests then this is definitely advisable (just don't use your best boosts that can be handy for levelling alts or gaining more karma).
