If this wasn't happening prior to an update, could it be related to the Secure Enclave/Coprocessor SEP operations?
Its not immediately clear to me if the Apple Studio Display, or your hardware includes the same co-processor that other Apple Silicon now have.
You've pretty much ruled out what you can do in software. Next steps would probably be voiding the warranty, finding the offending circuit branches or probing with a logic analyzer.
If you have an SDR handy, you might be able to get more information from RF emissions. I remember a fairly recent -thon talk where SDR was used as a side channel for debugging hardware/software. Not finding the talk now, but there was a tutorial on doing something like that here (below). The talk I saw used a Kraken SDR array with some customization to isolate signals to those emitted by the circuits being examined. Was pretty cool, really wish I could find it now.
Please update your Studio Display to the latest approved firmware. Can't believe we as consumers have accepted this reality.
It’s already at the latest firmware obviously!

The juice might not be worth the squeeze.
