Encoded upon request.
These BDs are incredibly blurry, which is pretty ironic considering it was mostly a sharp bicubic upscale. Filtering is pretty standard with a couple of fun caveats.

The show uses a mix of Spline16 and Sharp Bicubic for the upscaling. That is, some scenes are upscaled using one, others with the other. To deal with this I wrote an easy function that compares a Spline16 descale and a Sharp Bicubic descale with the original pre-descaled frame, and have it pick whichever it deemed to be closer to the original frame. This worked for the most part, except for very blurry scenes (where the difference is not really perceivable anyway, so it's not really a problem). This is not the end of the descaling issues, though. A certain scene in OP3 seemed to have been upscaled per field. This means every field (or odd and even sets of rows of a frame in layman terms) were upscaled independently, causing a very bad-looking combing-like effect on the lineart. I worked around this by simply descaling the fields independently, merging them together, and rescaling the combined frame. This had to be scenefiltered, but I didn't notice it anywhere else.

The rest of the filtering is fairly standard. Reupscaled using nnedi3, denoised using dfttest to get rid of compression gunk, weak CCD to denoise the chroma, decsized, AA'd using based_aa and sraa clamped together (with scenefiltered transposed sraa for specific scenes), very slight line darkening to offset the line brightening from descaling sharp bicubic, averaged debanding (f3kdb @ low settings + placebo @ low settings to deal with certain types of banding f3kdb couldn't handle), and then regrained.

Requests are welcome, but don't count on me to follow through with yours from the get-go.
