I can confidently say there are two types of people in this thread:
People who think the CW is any good at a DMC-like,
and people who actually know the CW is trash at DMC-likes, probably because they paid attention to the shows and the audiences they're for.
This part, especially. With how the CW has handled The Flash and similar Arrowverse shows, none of that will happen. The Flash by itself is proof enough that they don't give a damn about diversity to do it well. It's garbage at it. Among other things:
The star of the show will be Caucasian. Other ethnic backgrounds are supporting characters in an ensemble, and an exercise in tokenism.
The weekly conflict will be seemingly insurmountable every episode only for the episode to resolve with someone in the Diverse Ensemble Cast telling the hero to perform a basic action that he should intuitively know how to do. This ruins any existing mythos of the character being "self-made and intelligent" and the fault will be placed on the Diverse Ensemble Cast as if they're a collective vampire sapping the hero of their positive traits. The Cast will be blamed, and not the writers for not knowing how to write their hero.
The hero will perform some increasingly escalating morally repugnant nonsense based entirely around his sense of entitlement. Even though the hero is presented as straight-laced and Do No Wrong, his entitled actions endanger the Cast and/or anyone he's supposed to have basic empathy for. Excepting rare cases of justified anger towards the hero, the Cast mostly revolves around the hero to tell him that his own terrible choices are not his fault and how pure and morally upstanding he otherwise truly is, even if his existing attitude/entitlement might've rewritten reality once or twice or five times, caused a few ecological disasters if applicable, or happened to give rise to his own Villainous Future Self. These verbal head pats don't apply to any of the Cast with their own conflicts. If anyone else in the cast comes across a Parallel Universe Self, that version is unequivocally evil to sow doubt in the cast member's heroism. even if the Main Hero has met more Evil Versions of himself or villainous parallels/foils/whatever than anyone else in the show, and more than one version per season.
The hero will be a hypocrite who takes anyone in the Cast to task for the same actions he's done dozens of times over. When it turns out those actions and the result of them are actually his fault, it gets swept aside. In any event where someone in the Cast carries justified anger at the hero, some failure of a moral lesson will happen on them to teach them that they were wrong, even though they're not and the lesson itself makes no sense. The hero will continue to be selfish and entitled even though the rest of the cast has been through worse and had less excuses.
If the hero has a love interest that's not Caucasian, the writing will sabotage her, leading to fandom complaints that the Love Interest is boring, badly-acted, "like a sister" to the hero and not romantically viable (coming from shippers who'd pair the hero with an Actual Relative anyway as long as it's a dude), useless, should be killed off, etc. Not coincidentally, the love interest won't have her own story independent of the hero and might even behave in ways that inconvenience him such as being rightfully angry about him pulling off some morally repugnant nonsense, inflaming fandom anger more than usual. Even when a season in the show is About Her, it's really going to be About Him and how bad his pain is, because she's secondary to the point where she'll have the least amount of episode appearances in that same Season That Is About Her. IOW, think of how much the writers of DMC don't give a damn about Kyrie and the other women in the cast, and multiply that.
This has nothing at all to do with the Hero and what he looks like, compared to the Cast and what they look like. [/sarcasm]
That's all if the hero is a Barry-like character and meant to come across as a Moral Paragon. If he's an Oliver-like (anti-heroic), then the show will spend a bunch of time dunking on him for not being as heroic as he could be. Crossover episodes that involve the Actual Moral Paragon/Barry-like showing up to the Oliver-like's turf will have that Hero and his Cast dunking on the Oliver-like for not being as Good as the Barry-like, and teaching the Oliver-like the Right Way To Hero, even though the Barry-like casually does things like killing C-tier villains offhand and violating human rights on the regular, but preaching about second chances and sparing Parallel Universe Nazis or something because of an arbitrary No Killing Rule.
Or, to make it simpler,
Is the hero black, as well as the rest of the cast?
Dismissed as Woke B.S., cancelled after a few seasons (Hi, Black Lightning! .... Bye, Black Lightning!) or the show doesn't get past its backdoor pilot (Painkiller)
Is the hero a woman, as well as the rest of the cast?
Dismissed as Woke B.S., cancelled after a few seasons, or the show doesn't get past its backdoor pilot (Green Arrow and the Canaries) unless it's backed by Geoff Johns (Stargirl)
Is the hero a black woman?
Dismissed as Woke B.S. Immediately. (Batwoman Season 2) Pending cancellation after a few seasons.
Is the hero gay?
Literally who? (Batwoman Season 1)
But hey, good thing we have Yet Another Show About Superman.
