I am using Mac OS and created profile with ColorMunki Photo + DisplayCAL3.35
Please take a look at the screenshots
When viewing images by “Apple Preview” APP
The BLACK POINT on “Apple Preview” is DIFFERENT from
the BLACK POINT on “Finder Preview” (Correct Blackpoint)The BLACK POINT on “Apple Preview” is much darker,
Any Less than 4% on image is already Completly BLACK
but on “Finder Preview” it can still identify the differences between 1.6% & 4%BUT created profile with ColorMunki Photo + Official APP
When viewing images by “Apple Preview” APP
The BLACK POINT on “Apple Preview” is SAME AS
the BLACK POINT on “Finder Preview”which is normal
Because the new version of Lightroom Classic CC, use the black point as same as the images on “Apple Preview” APP
which is way too dark, so I can not use the profile created by DisplayCAL anymore.I have tried to check and uncheck the “Black level drift compensation” on the DisplayCAL, but it does not work.
Also, I had tried to set custom gamma and black output offset setting on DisplayCAL, it does not make any difference
This is not only happening just on one mac, My Mac Pro with an external monitor and my iMac, Macbook Pro, with different OS version also have the same problem.
Did I set anything wrong? or it is a bug on Mac? Thanks a lot.

2017-10-26 at 1:34 #9261Thanks Florian, but if it is a bug, why it does not happen when using ColorMunki Official App to create profile? it may be some setting in the profile file itself right?

2017-10-26 at 1:36 #9263why it does not happen when using ColorMunki Official App to create profile?
From what I’ve seen, literally coincidence. I’ve it seen with i1 Profiler, basICColor, and others (which is no surprise since it’s potentially a bug somewhere in the Apple CMM, not in the generated profiles).
2017-10-26 at 5:53 #9265But if it is a bug, the earliest Version I am using that has this problem is Mac os EI Capitan till now already 3 year, still have not fix this problem, is there any place we can report this problem to Apple? Thanks
2017-10-26 at 23:58 #9270There is a link to send a bug report to Apple in one of the other threads I mentioned.
2017-10-27 at 2:42 #9272Is there any technical term that can demonstrate this in short? or keyword I can use? thanks. is that possible can you provide the threads’ link? thanks a lot
2017-10-27 at 16:20 #9277Is there any technical term that can demonstrate this in short? or keyword I can use? thanks.
The important thing is that it is a rendering bug related to Apple’s color management implementation (doesn’t happen with e.g. Photoshop, only happens on mac). Just give them as much and as detailed info as possible.
is that possible can you provide the threads’ link? thanks a lot
Dark Images in Mac "Photos" & "Preview" with DisplayCAL generated Profile

SOLVEDIn my case…
I use EIZO display with its calibration software “ColorNavigator” and calibrated profile.
When a profile made with an option, “reflect black level in tone curve” is checked, shadows get too dark.
Uncheck the option and re-calibrate (= renew profile) fixed the issue.==========

about
“reflect black level in tone curve”
is DispCal has this option?We don’t even know if the person really had the same problem, neither do we know what “reflect black level in tone curve” does in the EIZO software. Discussion should continue in the other thread I linked above, I’ll close this one shortly to avoid redundancy.
