HDR photos display properly in Lightroom on Mac but appear too dim once exported
I'm editing on both an M1 MacBook Air and an M1 iMac. Both display HDR properly in the Lightroom app, but once exported, the lighting is not as intense--highlights are dimmed.
I've tried exporting in AVIF and JPEG XL, with all available color spaces, with no result. I've tried viewing the images in Preview, Safari, Chrome, and Photos, but they all look identical, i.e. a little too dim.
HDR Output is selected while exporting. A notice displays while exporting that "HDR is not visible in this preview," and the preview looks VERY dim, even dimmer than the final exported photos.
I've attached a screenshot here. Obviously the colors don't look like they do in real view, but you can see there's a difference. Left is the Lightroom app, right is the exported photo.

Everything I've read online leads me to believe that MacOS Sonoma should be able to display HDR properly. Does anyone know why they are not exporting properly?
