They are

The proper setting for sharpness is always0.
Also my Oppo BDP-103D is region free.
That makes me awesome.

What makes you think that? Looks like plenty of true black to me:

http://www.blu-ray.com/movies/screen...440&position=6

I just checked my Destoroyah disc and sure enough, switching to PC levels causes shadow detail to vanish.

The new Yojimbo & Sanjuro discs from the BFI (which annoyingly use transfers that are otherwise far superior to what Criterion used).

Interesting thread.

Severin's "Santa Sangre" looks like a candidate of this error, to me. The small amount of letterboxing (it's 1.85:1) look milky grey rather than black...

That definitely appears to be the case when you compare caps against the UK edition:

UK: http://www.blu-ray.com/movies/screen...786&position=5
US: http://www.blu-ray.com/movies/screen...178&position=3
UK: http://www.blu-ray.com/movies/screen...786&position=8
US: http://www.blu-ray.com/movies/screen...178&position=6

I'd say the US version is actually superior in every other regard though. Probably best to have that one and just correct for it.

The Godzilla movies that were not released as part of the TOHO SONY Collection (the latter look quite good from what I've peeked at). The two they got separate releases are awful. The levels are way off it looks like they fit things between range 80 and 130 or something .

Not at all. In fact, some seem to be encoded in double or triple reverse of that! They don't store black as 0 (as with PC levels) or even as 16 (as with video levels) but as 32 or even 48 like with those dumb two Godzilla releases.

First, I will first admit for the record that I have gotten my threads confused. I read back through this one and see there is little to no discussion of JP releases with regard to black level disparity. No, that discussion transpired on another thread--I think one dedicated to a specific JP release (a Godzilla film maybe?). I'll have to look for it. That said, I'm not a total mouthbreather and understand that the ntsc-j black level disparity SHOULDN'T apply to digital tv standards or digital media, hd or otherwise. But what I do know is that some JP dvd/bd releases (as with some north american releases of JP content) are plagued with an anemic black level that requires a small brightness adjustment to look right but an otherwise correct color space, which yes, I still suspect some are mistaking for a completely incorrect color space--as discussed here--in the case of some releases. Whether it's ntsc-j black level mistakenly applied or unnecessary compensation for such deliberately applied, I've almost ceased caring at this point. Though irritating it's a trivial annoyance in the grand scheme with an easy fix.
It is NOT a trivial fix. The two Godzilla titles in reference are complete mess. Also some people have programmed internal LUTs and you can't just change the brightness dial (which does NOT fix it anyway). One of the titles has so little difference between black and white signal that it seems like it is maybe 5bits per channel instead of near 8! The blacks are bright gray and the brights are not proper either, they are weak. Everything about them violates any known BD mastering standard.

Agreed. The SOny TOHO ones are the ones that get it right, when it comes to Godzilla.

Sigh. Actually, in some (many) cases the fix is, in fact, highly trivial. That would be because there are two issues afoot with the various releases plagued with weak blacks--some are authored with full-on incorrect colorspace as discussed here, others have correct colorspace save for a elevated gamma/black level, the latter case being easily remedied in precisely the way I described...well for those lowly plebeians without programmed internal LUTs anyhow. Good chat!
