I’m absolutely willing to buy Blu-rays, but what I’m worried about is there being no English dub/subs. For JJK in particular it seems that, at the moment, Blu-rays only exist for native Japanese speakers…

But it seems like it shouldn’t be that hard of a task for someone to rip the subs/dubs off of a ghosted English copy and paste it onto the unghosted Japanese copy… But I can’t find any. Thus, my quest for a service that doesn’t even provide a ghosted copy continues.

Just look at the image I included in the original post. It’s a comparison between several shots in Jujutsu Kaisen where the shot is ghosted+dimmed and one has not.

In order to satisfy laws for preventing seizures for a minority of children in Japan, studios are required to release their animations with these filters applied to certain scenes. However, the Blu-ray releases are not required to be released with these restrictions, so the animations released in that format are unhindered and can be viewed as they were intended to be viewed.
