Photoshop doesn't use 30 bit display depth, banding issues in light grey tones.

Hi there,

unfortunately this bug (https://community.adobe.com/t5/photoshop-beta-bugs/p-photoshop-doesn-t-use-30-bit-display-depth-banding-issues-in-light-grey-tones/idi-p/15224234?search-action-id=826312321878&search-result-uid=15224234) is still there and has not been resolved by Adobe. 

It temporarily worked with one NVidia driver (581.57) and reverted to the old behaviour with later drivers. The problem with the 581.57 driver was, that every display profile was ignored by Photoshop and set to sRGB by Windows which is not the correct behaviour.

So please, Adobe, investigate and fix this!

Thank you.
