The question is if it was made with a 10 bit color pallet, rendered and produced in it, and then televised or digitally availble for download as 10 bit
There are many shows out right now that can be downloaded as 10 bit. But the thing, I don't know if they are just converting it.
The benefits of 10 bit are such that it would still make sense to convert 8 bit material to 10 bit as it allows for smaller and better optimized files
The new episode of Pet no Kanojo is so generic.
