Some random thoughts looking over the pictures:
-They're using PADDs. I guess the show doesn't want to spend money on projecting a holographic image from the badges? In universe, I guess you have to wait until you become an officer before you get the privilege of a badge with holoprojectors?
-If the memorial wall (or whatever it is) lists the full names for everyone, why is Garak listed as "Ambassador Garak" and not "Ambassador Elim Garak"?
-Is the lady Jem'Hadar supposed to be a flag officer? She has rank insignia on her collar similar to Admiral Vance's that's not included on the regular officer uniforms. Then again, upon closer inspection, Holly Hunter has similar insignia on her collar and she is supposed to be a Captain, and indeed, I notice she also has the additional shoulder insignia 32nd century Captains had on Disco.
-On a related note, that stupid plate on the front of the collar from Disco is gone.
-Reno doesn't appear to have any rank insignia at all.
