thank for the app !

how does this app can perfectly displays hdr still images ? why does .jxr, .exr, .hdr, displays perfectly and why .tif is all dull and washed out from the same hdr .jxr source ? how does the app signal to windows that it s hdr content and makes the hdr/sdr slider not affects the brightness ? is there any other viewer with this hdr display capabilities or is the only one besides microsoft photo for .jxr ? also do you know something other than jxrlib to convert back an .exr, .hdr, back to .jxr while keeping the rec. 2100 color space, st. 2084 pq eotf ? what are the metadata or the tags that makes the images displays in hdr like that and what tag that make other images not displays in hdr like that ? nothing appears with imagemagick or exiftool between 2 version of the same .jxr screenshot 1 hdr the other sdr ? everything reports srgb while it s absolutely not the case for .jxr screenshots or .exr, .hdr exports.... where is the documentation for all of that ?
