Some of that depends on how much is budget verses what was done because of an individual show's artistic choices. For instance, before I'd seen JJ I really wanted Kilgrave to go full purple on us, but while actually watching the show the fact that they stuck to only to using the Kilgrave moniker never bothered me. It made perfect sense with the story they were building. Having Kilgrave walking around with purple skin would have undermined the series in some ways, because it would have made him so easy to spot. It plays in to the idea you can somehow just tell when someone is evil. "Well of course that guy is a narcissistic super-powered rapist! Hello? Is everyone blind?" I mean, they could have used it in a small way later (and half did with the.veins) but overall the story they told needed to be removed from a lot of those fantastical elements. JJ is purposefully given a nonfantastical no flash feel, and I'm fairly certain that was a conscious choice on the showrunner's part rather than a matter of down playing it because it's a Netflix program.
As for the radar sense, if I had to guess the lack of use stems from a need to separate the show from the movie. Or possibly the fact that it just looked kinda stupid. Well, no, it's probably not that. But I assume it's like the costume issue. I have to believe they purposefully held of on the final costume in season one because of the story they wanted to tell. Otherwise, why not use the fact that most of the earliest viewers would be coming from the moives and well adjusted to the whole costumed hero look unless they really wanted to build DD from the ground up? I mean, a lot of these things make sense for storytelling even outside of budgets or shared tones. Which isn't to say those elements don't play a role in shaping each show. Just makes it difficult to say anything for certain.
Although, yeah, I'm more inclined than not to agree. I think the series will focus on Danny in NYC and the Kun'Lun elements will be left more to mystery. I do not expect to see Finn Jones hug a dragon to sleep on screen despite how amazing it sounds on paper.
