Why is nobody talking about the standards development? They (OS, image formats) could just say all stuff by default assumes SDR and if a media file explicitly calls for HDR even then it cannot have sharp transitions except in special cases, and the software just blocks or truncates any non conforming images. The OS should have had something like this for sound, about 25-30 years ago. For example a brightness aware OS/monitor combo could just outright disallow anything about x nits. And disallow certain contrast levels, in the majority of content.
