I work in the control room for an electrical generation system an this isn't the case at all for us.
Each desk has 12 ~30 inch monitors, and each monitor has a similar degree of information density, from monitors of system frequency, voltages, power flows etc. around the network, also financial / market information. There's a mix of diagrams, tabular data, maps, plots.
Two of the monitors are devoted to a geographic view with weather data, locations of field staff etc. Check out the similar setup from this California control room: https://www.bizjournals.com/sacramento/news/2016/06/17/calif...
Most displays show live data, but are not setup to be interacted with normally.
I think the truth is probably due to: 1) the same with all enterprise software, the folks who end up using the displays have token-to-no input into the purchasing or design decisions. Actually now I think of it, check out the interfaces marketed to electronic music composers (generally individuals or small studios): https://www.youtube.com/watch?v=GOq8R55xMyo
2) While I bet operators would select Tronish UI given the choice, they don't _need_ it because ultimately (with enough experience) the model of the system sits in your head, and the interface simply gives cues.
