Do different dungeons of the same tier have different loot tables?

[Vidu]

Nope, dungeons released at the same time drop the same loot at the same rates. Just bad RNG.

This is only true for the HW and SB dungeons - in ARR the loot tables used to differ.

So while it doesnt matter for the OP, since Ala Mhigo, Kugane Castle and Temple of the Fist have indeed the same loot tables, I wanted to add this for a more accurate answer!
