OK, so, what you're doing here is parroting a study that showed that fast-paced slop content like Cocomelon was bad for developing brains, but you're missing some key points. The takeaway from that study was that fast scene changes, constant music, and bright colors/motion were harmful to kids. These factors prevent kids from processing what they're seeing and condition them to seek constant stimulation.

That is very different than something like Paw Patrol, which (even though I think it's boring drivel), tells a coherent story over a 12 minute period. Whereas Cocomelon is basically just visual noise played over constant children's music, the Paw Patrol characters have to stop, give exposition, and talk to each other. There are breaks where the characters (and viewers) slow down to process information in order to form a coherent narrative. It's not a very good or educational narrative, but it's not actively harmful like Cocomelon.

Also, funnily enough, I just came across an article that happens to have statistics on Bluey's scene changes, and they average 4-6 seconds (compared to Cocomelon's 1-2 seconds) and ranked nearly as high as Daniel Tiger in terms of, "Calm Engagement."
