Deficient handling of areas of blacks and shadows in ACR

Recently I was playing trying to reveal a hidden text in an underexposed area. Camera RAW could not show it while other programs including the Preview utility in Mac OSX and Luminar, Exposure, Affinity and CaptureOne did it without problems. I have always thought that Photoshop and Camera RAW are the parents, the origin of the other programs, so it is hard for me to take on this problem that on the other hand may not be so serious.

If I open the JPG file directly in PS and then I go to ACR, no problem the text can be seen moving some controls; but if I open the file directly in Camera RAW, it is not possible.

I'm a Mac user and all the software involved is up to date.

I attach the test file. 40035943_10214123535536569_2220485701051351040_o.jpg

Thanks in advance for your attention.

The OP is describing a problem with JPG-handling in the ACR plug-in.

The JPG under question is in the first post, just download and try it for yourself.  This has nothing to do with raw processing.

More significantly, LR acts the same, so there's no way to get to the darkest few tones when editing a JPG.

Today Adobe released Ps 20.0.2 It seems that this problem has been corrected. Thank you Adobe.

"The raw metadata for some Photoshop files has excessive number of entries of 'photoshop:DocumentAncestors'"

If it has been fixed, it has nothing to do with DocumentAncestors - which does not apply to raw files from a camera. That's an issue with excessive amounts of edit history metadata, bloating file sizes.

The problem with the black scaled profile is apparently that it interferes with normal Black Point Compensation - a standardized procedure that works very well when left to its own devices. I suspect the black scaled profile is intended to be used with applications that don't do BPC at all.
