You do realise that almost all of the current anime are not composited at 1080p, right? Most now are composited at resolutions at 720p or higher, and rarely at full 1080. Actually, Garden of Sinners was composited not at 720p, but around 540p which is half that of 1080, exactly like Fullmetal Alchemist Brotherhood.
Gankutusou was composited at 480p, and Bloodlust (if you're talking about Vampire Hunter D Bloodlust) as composited digitally at some resolution I don't know, but as the original files no longer exist (or something to that degree), a 35mm print was scanned at 2K for Discotek's BD (which AL replicated).
I remember when Naruto Shippuuden started airing, and it was a big deal that it was widescreen instead of 4:3 like the original series. It hit me back then that anime was behind the curve and/or didn't much care.
I knew Ganku and Noein were standard definition, simply because I watched them around when they came out on the internet. The Blu-rays were such obvious upscales; the images lacking sharpness to the point it wasn't much difference than the DVDs. Noein especially disappointed. Nowadays I've come to accept only old school cel anime and not 2000's anime on BDs will look razor sharp. A pity when mid-2000's anime was where I found many of my favourites.
Didn't Perfect Blue have a similar issue to VHD: the original materials being lost/the BD underwhelming? I'm hoping Millennium Actress looks a wee bit better. Come to think of it, I thought that was out...
...oh, KnK: no, I didn't know that was originally 540p. I read that Brotherhood's DVDs looked as good as the BDs, and I recall thinking my imported DVDs looked good, way back when. For the record, I thought KnK5 looked fine. Tbh, I don't understand how modern anime is created; just that digital anime would have to be remade to go above the resolution it was created at. Or something like that. I think. Maybe.
