It's the type of story that sensitizes you to awareness of the pattern.
That the victim in the OP story got access to an attorney of any color—even dragon-purple—actually puts them above the median.

"Ciavarella disposed thousands of children to extended stays in youth centers for offenses as trivial as mocking an assistant principal on Myspace or trespassing in a vacant building.[3] After a judge rejected an initial plea agreement in 2009,[4][5] a federal grand jury returned a 48-count indictment.[6] In 2010, Conahan pleaded guilty to one count of racketeering conspiracy and was sentenced to 17.5 years in federal prison.[7] Ciavarella opted to go to trial the following year. He was convicted on 12 of 39 counts and sentenced to 28 years in federal prison.[8] Conahan, who had been released to home confinement in 2020, had his sentence (due to end in 2026) commuted in 2024 by President Joe Biden."
His constituents petitioned him about the crooked jails, and... Biden heard them; and freed the jailer.
The willingness to take the optics hit to allow him a little more freedom, a little earlier makes me question what everyone else is leadership is doing, they must really relate to him.

The breech of formality isn't being turned into a big deal because it might bias case outcomes; in that regard it's a rounding error washed out by innumerable more substantial sources of bias. It's being made into a big deal because formality is the wall between outcomes of cases and feelings of personal culpability for the people who are involved in that process. All of the formality and decorum make it easier for judges and lawyers to emotionally distance themselves from, very often, ruining peoples' lives.
Also, just because the other potential sources of bias you brought up exist doesn't mean new ones should be let into the process. I wouldn't be against solutions to remove the ones you mentioned. But I don't think you'd be entirely convinced that just allowing cartoon dragons would decrease bias by making people more empathetic.
Trying to make this about "more significant and well known biases" when all I'm arguing for is not introducing additional biases is a logical fallacy. And allowing cartoon watermarks in court documents would not help with the "more significant and well known biases" that you're more concerned about, anyway, so I have to wonder why you feel strongly enough that this should be allowed that you'd write off opposition as "bikeshedding."

There are certainly bad judges that hide behind "the authority vested in them by the court," but reductively asserting that formality is about maintaining authority misses the point (and the operating philosophy behind creating a fair and impartial court) by a country mile.
