Anime fans can be a bit ridiculous but at the same time some of them accomplish impressive things. They've pushed AV1 (and other) encoders forward substantially. A number of older shows that were never going to get a remaster have been made much more pleasant to watch thanks to downright obsessive restoration efforts. They've also salvaged at least a few horrendous remasters that would otherwise have never been fixed.
Amusingly they're responsible for the propagation of the leaked DCP versions of several titles despite the fact that even most fairly high end devices aren't capable of playing such videos back due to the hardware being insufficient.
I still find it hilarious that of all things people pirating cartoons in their free time ended up driving a significant amount of codec tooling development. I wonder how you'd calculate the broader net economic impact of such an outcome.
AFAIK fansubbers were the first to adopt 10-bit video, way back in 2011.
I'm a 50-year-old Japanese person who watched the original Dragon Ball broadcast on TV around 40 years ago. Back then, there were no LCDs or OLEDs—only CRT ("brown tube") TVs, and the signal was analog. With that kind of analog rendering, it was practically impossible to tell what the "true" colors were. Plus, CRT displays degraded over time, shifting colors toward brown.
The pre-processed raw images in the article actually look like what I remember as the real Dragon Ball colors.
OTOH, the result looks great, so good on the passionate fans who spent their time and effort doing this.

ブラウン管 means Braun tube, named for its inventor.
I still remember as a child wandering into a bar on an afternoon, in a lost rural village in the middle of nowhere near the mountainous region in southern spain, now nearly 40 years ago. 2 old farmers were having a beer, the whole bar was totally silent, everyone watching the Dragon Ball episode on the tv. It was intense, the saiyans had just arrived.
It really surprised me ( as I did not realise adults watched it) and also because I thought on this trip to the countryside I would miss the episodes ( never to be able to be seen again). No internet back in the day.
Honestly, farmers watching Dragon Ball 40 years ago en el campo.

When I read the responses to this document, I wonder if Dragon Ball is the same, where the collective nostalgia is actually quite diverse.
They basically merged the Region 2 (Japan) Dragon Box DVD release with the Region 1 (NTSC USA) one.
>This merge of the two Dragon Boxes aims to get more detail at the boundary ranges of luma in order to obtain a higher dynamic range in a natural manner, without artificially distorting the luma through sigmoid-like functions. This is made possible due to the brightness difference between the North American NTSC and the Japanese NTSC-J standards and how the DVD compression codec (MPEG-2) handles this difference. Basically, MPEG-2 gives more 3 bitrate to brighter areas. Darker areas get less bitrate and so the image details there are blurrier and often destroyed. Fortunately for us, the North American NTSC standard has brighter blacks compared to NTSC-J, which means that MPEG-2 was able to allocate more bitrate to the dark areas on the R1 Dragon Box compared to the R2J, even though the latter has a higher overall bitrate. In addition to better dark details, the R1 Dragon Box also has more dark details. This is because DVDs have a limited luma range, and the brighter blacks on the R1 allowed more dark details to pass through that limited range. These same extra details missed the cut on R2J and were clipped away instead. So what does all this mean? It means that the R1 Dragon Box has better preserved dark details while the R2J Dragon Box has better preserved mid-and-bright details.

And then this merged release were used for the color correction
