So far there has not been a confirmed Pegasus infection with lockdown mode enabled. It's certainly possible but will require more sophisticated exploits, thus increasing the price per infection.
I will assume that unless the cost per infection is a staggering number, if a "baddie" wants to "get in" they wouldn't be phazed by $50k or $100k.
I assume that the value of the intel collected (contacts, eavesdropping, etc.) would be far more valuable as it would reveal whistleblowers, opposition tactics, contacts, candidates to fall off windows/balconies, candidates to be chopped up, etc.
