Seems I was probably wrong about 4K/DV streams. At least some (probably including Apple) seem to use a different approach for DV that seems to jive w/ your thinking than what 4K discs do.
I can't say I found definitive info (and have complete enough understanding of such), but seems that...
Actually, would disabling HDR/DV even solve the issue? Not clear to me if that would be so.
Isn't at least some very substantial aspect of the HDR baked into the video and can't actually be "disabled"?
Certainly, there doesn't usually seem to be some simple/straightforward way to yield...
Doesn't outputting 4K SDR kinda defeat the point of HDR, especially DV?
Not that I think (at least) some of these catalog titles should have had DV applied in the first place...
Note I'm not talking about WCG, just HDR, especially DV...

Not sure he's saying any of those 4K releases should have such "excessive HDR" where unwarranted (and breaks from original filmmaker intent). Rather, he seems to be pointing out a prevalent practice of false advertising that claims to use HDR, but aren't meaningfully doing so.

Maybe it'll be like Blade Runner 2049 and not really make substantive use of HDR, which is probably just as well...
Might still benefit noticeably from expanded color space of the 4K format though...

All for a solid 4K release... very preferably on disc, not just digital, but a tad skeptical of the Dolby Vision (or even HDR10) use/branding. Hope there's no weird, revisionist, funny business w/ the HDR processing...
