I think they have some of the best done 5k. It's on par with what most advertise as 6k-7k.
That being said, cvr and badoink is an example of higher resolution done right. I dont know the process involved, but I assume it has to be done with some custom camera builds.
Obviously I would love higher resolution as well, but only if done right. But again, keep in mind resolution is not everything. I'm no camera expert, but I think frame rate, and other aspects are just as important, and a lot of other places do some sort of upscaleing of videos, which don't add much if done wrong.
But higher graphics are always on my wish list.
