Well, this is still early in SW timeline. There's nothing to say he doesn't get promoted to Grand later.
I think we'll have our answer during SW celebration either way.
I seem to recall that Thrawn was not a Grand Admiral in TIE Fighter until round about the end.
As a point for consideration .. how much research do the movie makers put into these things? We nerds are going to over-analyse every single scene, prop, word, etc. But I'd argue we're a minority. Most people who see this film will be your average fair weather SW fan who couldn't even tell you the name of Luke's wingmen in the Yavin battle, let alone what helmets they wore.
Despite being an interesting topic of conversation ... is it possible that we're looking for something that is just simply not there? Maybe Disney just applies the Rule of Cool to Imperial uniforms, AT-AT design, character names, etc. within the design space that identifies the character's affiliation, vehicle ,etc.
Actually, they put a lot into it. Academy Awards are on the line. Plus they derive their own personal pleasure (and reputation in the film industry) from the quality of their work.
Everything you see on screen was carefully - or carelessly - put there by someone with deliberate thought and intent. Everything was designed by someone and (likely) made by someone else. And you don't get involved in the making of a film like a Star Wars movie by being sloppy.
Just for reference, based on helmet decorations:

Wedge, Wes Janson, Davish Krail (Pops), John Brannon, and Wenton Chan are in the trailer.
I'm not sure that those helmet designs are made for entire squadrons...I often wonder where those helmet designs come from. I personally doubt that the pilots you named are the ones in that still (It would be neat if you were right, though).
Not sure what you mean, the various X-wing pilots shown on-screen in the movies indeed have their own unique helmet designs. Wedge wears the same one in both ANH and Jedi, for instance. Some of the helmets in the screengrab do indeed seem to match up to pilots from ANH; Wenton Chan and Davish Krail specifically. Others not so much; The one that is supposedly John Brannon is missing details and has the wrong color at the 'nose', Wes Janson has been discussed, 'Wedge' is hard to tell since it's not entirely clear what angle he's holding it at, but it looks like the area that's over the ears is gray instead of white. All that said, it's not unreasonable that's who these guys are, given this is very clearly the base at Yavin IV and they were all stationed there. Curious to see if they're involved at all or just background nods.
It's not like nobody's ever lost their helmet before. Or had it damaged and had to replace it or touch up the paint. Or inherited their helmet from someone who died.
Why would anyone train in martial arts at all today when we have guns?
Because it's a hobby, because it keeps you fit, because it's part of your culture, because you like it, because you want to compete in it...
People in Star Wars just get to ALSO use it in combat situations when they can.
A- The proper utilization of a firearm is a martial art.
B- The use of melee weapons can be ceremonial - think of the Pope, protected by his brightly colored Swiss Guard (Emperor Palpatine is, in many ways, an evil space Pope).
C- The martial art that you compete in, practice as a hobby, &c., is more likely to get you f___ed up. The martial art you use to defend yourself from someone while unarmed or with improvised weapons is not the martial art you learn in your average karate dojo. And most of the people with the most experience fighting people to the death while unarmed, with knives, baseball bats, or other weapons, improvised or otherwise, have never set foot inside such a place.
