I never quite understood the concept of the culture worker job: what kind of job would that be in real life? E. g. people working in museums are not the ones that create culture, it's the artists who created the art presented within the museum who created culture! But, given that one pop represents many millions of people, we cannot reasonably think that there is even the equivalent of one pop creating the culture on any planet: at best it's a fraction of a pop!
Therefore I like the new concept of using monuments - without jobs - rather more reasonable. The task of the bureaucrats, then, is not so much to create the art, but to present it and make it available to the public: people working at museums, etc..
As @Dragatus mentioned it is just an odd naming choice for the job. The job itself was also washed up after the Federations patch, which made monuments and heritage sites not planet unique AND ALSO totally useless. In earlier patches you needed some of these buildings here and there to get more unity, especially when a (working) sprawl mechanic was in place, which is not the case in the current form.
In my view you have can draw a line between on what entertainers are and what purpose "culture workers" have to your special kind of empire. Entertainer are there for fun (as mentioned, movies creators, sports and so on, stuff that distracts the population but has no pilitical influence), culture workers should represent the lower administration of your empire and these can vary extremely.
And also, bureaucrats are just a niche for some empires (authoritarians with shared burden anyone?). It would be very immersive if spiritualists for example would have priests as rulers and, for example, monks as lower administrative class created by temples, not administrative offices. Militarists could get a building called headquarters, which creates Military Officer jobs, Megacorps get the managers, feudal societies have knights and so on.
Everyone of these jobs creates unity and should fullfill another role special to the empire type. Managers generate some extra trade value, Military Officers some naval cap and hard defense armies, egalitarian judges stability, materialistic sociologists grant some extra research... This would add so much flair to different empire types combined with some real game value... but...
