Hi Tyler, I’ve been doing some similar testing with a project I’ve been building in Final Cut Pro X. I work primarily with night photography so as you can imagine, I’m quite sensitive to the tonal degradation we typically see in the shadows in video.
I’m not sure what options you have in iMovie but, FWIW, I’ve discovered that the color space is of little consequence, but the format is paramount. If I maser video in the PreRes 422HQ format (or higher) then there’s no visible degradation. PreRes 422 and lower, including the notable H264 format use compression that’s pretty terrible on the shadows and since most delivery methods require H264 (like Vimeo and YouTube) we’re really limited. I’m hoping that H265 will improve the quality here. In the meantime, I’m exploring using media players that allow playback from H265 and uncompressed formats. Again, I’m not sure if this helps you with iMovie but hopefully this sheds some light - it’s the compression format we need to focus on - not the color space.

I've tried a variety of import methods (tagged tiffs), including pre-converting all files to HDTV, sRGB, GenericRGB, etc, and iMovie totally hammers near blacks with loss of continuity and bad color crossovers. I've also tried various export methods, to no avail. Problems are most obvious with B&W imagery but close inspection of color reveals the same problems.
