SpaceX probably spends a lot of money on marketing/public relations creating great media. I'm guessing NASA's on a shoestring budget for that kind of thing.
SLS was far from a shoestring budget and both NASA and Boeing/Northrop/etc have equally strong incentive to provide solid coverage for the public to keep the jobs program going.
SpaceX has much better infrastructure for video with their satellites and are just generally more competent at production
Not just space-potatoes… but missed the separation shot on the live feed. How in the hell!?
