The only time I have ever watched fireworks on the TV has been for things such as New Year celebrations around the world. Some countries still do fireworks and others opt for fireworks and drones which are nice to see.
I really don’t recall the last time I watched fireworks live on the television, but it was a New Years celebration years ago. I prefer to actually go to my hometown firework shows in person. More fun and exciting to me.
I only watch fireworks on the TV on New Year's Eve but most of the time that is on, I'm watching the neighbour's fireworks outside.
Other than that I don't bother watching the fireworks on the TV.
My husband has PTSD as well as I but his is from the military. He hates them so we usually don't go out. I love them though so watching them online. Very pretty.
