Delve Chest - Hidden Opulence

I feel like the Delve "Hidden Opulence" lost a bit of their lustre when the defacto trade currency changed from Exalted Orbs to Divine Orbs. The chests are very rare (this league I have seen 3 total pushing to depth 900), and when I used to find one, I got so excited knowing there was an extremely high chance of getting an exalted orb (back when that was the defacto currency). Now, when I see one, it is like "will I finally get a divine from one of these? nope, another exalted". They seem skewed to drop Exalted Orbs rather than Divine Orbs, even though, to my understanding, they should have roughly the same drop rate in the wild. But this is just anecdotal, and based over the last few leagues.

Any chance we could get the drop rate of the chest evaluated to see if it is infact the case, or if it is just my observation bias.

Thanks!
