I gave the new Disillusion only one listen, so it's early to say...a lot to digest, but it sounded good. However - and I know they are different - if we stay within a broadly defined "heavy prog" genre, I didn't feel there were moments as immediately striking as, say, the Abstract Illusion record. The latter is much heavier, for sure, but there are some shared traits in terms of soundscapes and long-form tunes...
Sounds super-promising, though, and I'm sure it's a grower.
Litho - I'm not sure I hear a lot of "melodeath" (as codified by the sound of the various bands you mention) in here. I think Back to Times of Splendor had some traces of it here and there, but even that was more of a "progressive" affair than melodic death metal.
