In the US, the trend in TV news is to blur-out anything that shows blood, missing limbs, etc.
I think also because it was unexpected. The text (and the music) made it sound like a romance music video or something, so people would not know what was coming.
I know CW's are difficult to determine. I usually avoid them unless it is something really shocking. But what is shocking to me may not be shocking to others and visa-versa.
Of course qoto is very permissive, I was thinking about other folks on fedi that may be more sensitive.
