I read here that bpg supported since PG is supported 6.9.0-4. version http://www.imagemagick.org/discourse-server/viewtopic.php?t=26880 $ rpm -q ImageMagick ImageMagick-6.9.2.7-1.fc23.x86_64
Thank you very much for the bugreport and willing make free software better.
Thee problem there what ImageMagick delegate such work toy bpgenc which is part of libbpg (http://bellard.org/bpg/). And last is not yet in Fedora. There nothing to do with it in ImageMagick. It libbpg itself seams interesting for me, but there some words about patented codecs used. Citing: "Some of the HEVC algorithms may be protected by patents in some countries (read the FFmpeg Patent Mini-FAQ for more information). Most devices already include or will include hardware HEVC support, so we suggest to use it if patents are an issue.". I'll try clarify it.
Unfortunately due to the legal issue https://bugzilla.redhat.com/show_bug.cgi?id=1314506 I can't bring that support into Fedora distribution. Sorry. Meantime you could use it from my repository: http://rpm.hubbitus.info/Fedora24/libbpg/
