[AP2.x] opening JXL files assigns the wrong color profile

[F_Kal]

There seems to be something off with the rendering of jxl files (or at least jxl files converted by cjxl)

If I take a HDR .png file generated by Affinity Photo with an icc profile of BT2020 (Linear) and convert it to .jxl using cjxl (eg. by cjxl P8159638.png P8159638.jxl --modular=0 --effort=9 -d 0.2 --brotli_effort=11 --intensity_target=1000 -v -v -v -v -v -x color_space=RGB_D65_202_Rel_SRG) the resulting .jxl file when opened back in Affinity Photo appears as RGB_D65_SRG_Rel_Lin which is simply sRGB, not BT.2020. The image opens also very dark.

Apple's Preview inspector shows the proper colorspace profile for both the png and the jxl image. Unlike Affinity Photo that doesn't respect the ones found in the .jxl file.
