This. Anecdotal but we don't have both sides picture.

I was dev contractor in a place where everybody worked 5x 9-5 except one full-time person in the team who bragged at the Monday standup what they did over the weekend. Their contribution was very poor, they couldn't really fit into project objectives without drifting away from them each time, work was ball of mud committed every two weeks at most. And that person supposedly has had to be with years of professional experience. It seems they got too comfy in the previous roles as their self-development stopped in some 2000s tech maintenance.

Feedback and hand-holding didn't help, that person had to be laid off in the closest round. I think their spouse would say about 150-200% commitment, but then the other team members had to spend 1/3 of own's 100% to clean up that person mess.
