Correct, the bridge of a Star Destroyer and a Super Star Destroyer look very similar so you'd be hard pressed to guess which ship they're inside of in that scene.
The Star Destroyers in the new movie have a different design, reminiscent of the Sith Cruisers of the Old Republic, hinting perhaps that the First Order is more turned towards a religious or cultist aspect than the Empire. It's my belief that as much as the Empire and various Imperial designs were based heavily on WW2 Nazi designs (officer suits for instance), the First Order in the new trilogy is based on the much more hardcore-believers SS (extreme even by Nazi standards), and the suits also reflect that. So, their First Order being much more into the occult is likely, since the SS were led by Himler who was a nut about everything occult (rituals in castles and shit, it's crazy).
Supposedly, there were twelve executor-class Star Destroyers in the Imperial Navy, the only one seen in the movies was the Executor, and only one other is official as of now, the Ravager (mentionned in the canon book, "Lost Stars", awesome read by the way). Fun fact, it's also the name of Darth Nihilus's personnal flagship in KOTOR 2 but I'm sure that's a coincidence, it's just a badass name.
This may or may not be the overturned Ravager seen on Jakku, since there WAS a "Battle of Jakku" before TFA happens, and after the ending of the canon "Lost Stars" book. The end of Lost Stars (not really a spoiler) features the crash of the Star Destroyer seen in the trailer on Jakku (The Inflictor), so it's definitely all canon and official.
What has me curious about that scene above though, is what they're all looking at. The red flash looks like it's not coming from a star, so I wonder if perhaps they're looking at a shot from the Starkiller Base superweapon.
EDIT : haha I was replying to a past from the previous pag and by the time I was done writing, there was like ten posts before mine.
