Is it just me or are Drop Rates much higher in dungeons than they are if you're hunting in the field?

As an example, the Small Getas from Stickys, or an even more common example, the Gloom Daruma shards from, you guessed it, Gloom Daruma. In dungeons, they will drop practically every single kill, but in the field, they'll drop maybe 2/5 times.

I'd understand the drop rates being higher considering the enemies are often tougher in Dungeons, but I can't be sure. There's most likely a loading screen message that I'm missing.
