Max Damage
I have a 62 IV DB/DC Dragonite. 9 atk, 9 def, 10 sta IVs. It's my only Dragonite and I tend to not power anything up below 85% IV's, but because of the legacy moveset, I'm tempted.
Will it hit a point where the damage output reaches a cap and it wouldn't make that much a difference?

Depends on defender.
As an example, for Mewtwo raid boss:
Dragon Breath caps out at 5 damage at level 23.
Dragon Claw caps out at 42 damage at level 39, but is already 39 damage at level 30, and is 34 damage at level 23 (since I already referenced that level).
It has has defensive breakpoints against Confusion at levels 23.5 (22 damage, 5 dodged), 26 (21), 28.5 (20), 33 (19, 4 dodged).
Fow Tyarnitar raid boss, Dragon Breath caps out at 5 damage at level 30.5.
I'm looking at the spreadsheet named "Damage per level against fixed defender". On my phone right now, so difficult to search Reddit for it.

DB/DC is a good moveset, but DT/OT is just as good if not better. I had a DB/DC dragnotie and TMed it to DT/DC. I still feel like Dragon Claw is sub-par compared to outrage and even hurricane. But I'll keep it bc it's rare.
If it were me I'd stop powering up that dragonite and power up a higher IV one. With the TMs everywhere you can change it to any moveset you want.
