What free software PDF readers claim they support ISO-32000-1?

How many actually support it, including e.g. JPEG 2000 compression? (Can someone link a test case?)

I'm interested mainly in answering the question for software listed in https://pdfreaders.org/, which I'm not sure were fully assessed for standard compliance.

There is no PDF viewer which is fully, and completely compliant to every item in ISO-32000 (as far as I know).

The closest is Adobe Acrobat (Reader).

There is also no formal testing environment for ISO-32000 viewing compliance: We do not have any set of reference files which have to display properly, in order to conclusively make the tested PDF viewer "ISO-32000 compliant".

As for JPEG 2000 support, I tested a few viewers and these manage to open it: Okular, Evince, XPDF (okular-14.12.3-1.fc21.x86_64, evince-3.14.2-4.fc21.x86_64, xpdf.x86_64 1:3.04-11.fc21).

I failed with: mupdf-1.5-5.fc21.x86_64 (segmentation fault), zathura-0.3.2-1.fc21.x86_64 and qpdfview-0.4.13-1.fc21.x86_64.

My test case was created with img2pdf from JPEG 2000 (JP2) images produced by ImageMagick 6.7.7-10 (+ JasPer 1.900.1-14ubuntu3.2) from 4-bit grayscale TIFFs about 30 MPx big.
