BDMV is overall fine. First time in a long, long time that I've had to dehalo a 1080p BD. OP \*seems\* native 1080p, but I'm not entirely sure. To be safe, I didn't descale it. Instead I used upscaled_sraa to deal with the aliasing, did some minor dehaloing, and then proceeded to run a standard filterchain over it (adaptive denoise, deband, and grain).
