I can't remember how bad banding was on the imported Blu-ray of Castlevania. I did notice it, though. What I can say is AL's release of Ajin had far more severe banding, and that was left as is. I think it's an issue with Netflix releases: stream quality on disc.
Anyway, when I pre-odered Re:Zero, I thought 'why not' and preodered Castlevania: getting rid of my import copy. I own the no-logo VHD: Bloodlust CE, and thought another black+red spine would go with it. But for whatever reason, AL have gone back to adding those gaudy logos, as seen on Kokkoku. I didn't check before ordering Castlevania 'cause I thought they were a thing of the past. Also, as lovely as the glossy-paged booklet is, the pages stick together as if glued due to a lack of friction. Still, it is a nice enough release. And the ever excellent AL customer service refunded me £5 when I ordered after I missed the email code.
As for Re:Zero, no complaints there: a wonderful art box with no 'A' logoing and all artwork. Can't ask for more. I'm glad there's an outer box to hide the... purple-white snowflake irl wallpaper pasted along the bottom of the individual sets. Just need non-banded pt1 discs now.
Probably my last anime purchase for a long time due to money and anime watching struggles. Thanks to AL I've watched stuff I wouldn't have otherwise, like Belladonna of Sadness and Arete. I just wish they could be consistent with release style and delay randomness.
