There are 2 ways to deal with colorspace of a JXL codestream.

When exporting to AdobeRGB or ProphotoRGB Lightroom always produces lossless JXLs with ICC profiles and those files interpreted by color management of xnviewmp without problem.

If JXL is lossy by defaul it uses CICP-style Enum values ...

I guess xnviewmp internally has 8 bit processing pipeline and 16 bit images are converted to 8 bit before any manipulation. Right?
Is it impossible to correct this 16 bit JXL color profile issue?

I don't wanna archive 8 bit files because JpegXL it so good that 16 bit files are about the same size ...

Using ver. 1.8.0.

Still not showing correct color profile for 16 bit files.

Edit: My bad, I didn't tested 8 bit files. You are right, works for them, but not for 16bits.

Great, can I try that new build? Or maybe you are talking about 1.7.2?

Thank you for the updated version.

Unfortunately 1.7.2 did not fix the issue explained above. Color profile section of the picture properties shows "RGB_D65_SRG_Per_SRG" (sRGB) on all photos regardless of the real profile it has in it and treats them as sRGB color space data. Check with sample jxl ...

If you mean whether works all said above with 1.7 or not then answer is NO. The same problem as in 1.6.2-1.6.5. Detected profile is wrong.
but
If you mean the trick replacing the plugin only, this works up to 1.6.5 but in 1.7 plugin crashes and file is not shown.

All testing done in windows 11.

One more thing:

We can replace libJPEGXL.dll with one from 1.6.1. This simple trick works nicely up to 1.6.5 but not for 1.7. In this case plugin is crashing and JXL image can not be shown.

BTW Jpeg XL code of this plugin is quite old.

BTW I saw these issue https://newsgroup.xnview.com/viewtopic.php?f=62&t=46279 and its solution https://www.xnview.com/mantisbt/view.php?id=3052#history .

I guess trying to make HDR images showing up ""correctly"" can be the real issue.
I have DCI-P3 D65 (aka Display P3) calibrated/profiled monitor ...

Hello everyone,

Since version 1.6.2 JXL Embedded ICC profile is not detected correctly.

Jpeg XL has builtin profile naming. For example RGB_D65_DCI_Per_SRG means: color is RGB, WB is D65, Color primaries are DCI-P3, Intent is Perceptual and Transfer Function is sRGB. Rec2020 is coded as RGB_D65 ...
