Heniochus diphreutes or acuminatus?

Saw this in LFS today, it is labeled as acuminatus but looks like diphreutes to me based on the anal fin and number of dorsal spines (12 as opposed to 11). Does anyone with ID skills have any thoughts? I'd hate to get the wrong fish and lose coral, thanks!

Looks to me like diphreutes. This is due to the way the lines/bars are as well as the dorsal spines.
The belly is also rounder and the snout is broader. The anal fin is more pointed which is a characteristic of Diphreutes.
