Video Editing

I have a sequence in 2100HLG (rec2020 color space) that I'm trying to export in hevc (h265) for submission to youtube. I'm pretty sure I'm doing everything right, but youtube refuses to publish it in HDR...

Using the guidelines here: https://support.google.com/youtube/answer/7126552#zippy=%2Cupload-requirements

I've tried several exports, but the most exact to their specs are the two following mediainfos:

Is there something glaring I'm missing?
