In the given case it is not even clear what a "fully accurate" interpolation actually is. The kind of interpolation I used via DCTFilter certainly is of the sort "it does make sense". If it is "correct" or "accurate", that is playground for arguing.
If anything, I would be more concerned about the 6x6 -> 8x8 transition (which is ugly and can show up with some certain settings), or about why it's not possible to use one Deblock base for both processing paths (deblock is always called two times), or about directed border-postprocessing on the diff's, or .. or .. or ....
