Is televising sanctioned executions cruel and unusual punishment?

In California this week Governor Newsom changed all death penalty convictions to life, without possibility of parole. One reason is that the death penalty isn’t a deterrent if no one isn’t being executed, and no one in California has been executed by the government in 13 years.
So, if executions return, it would make sense to broadcast them on television to enforce their effectiveness as a deterrent.
I foresee a television show showing the prisoner marching down the hall, towards the death chamber. Then, a 10 minute review of the crime and the victims, and finally the injection or whatever.
It would be a ratings smash, and certainly would deglorify crime.
But would this violate the Constitution’s cruel and unusual provisions?
