Thanks for the quick reply! Alright, that's a bummer but understandable. Seeing the HDR triggering got me thinking it might be a user/setup problem. I'm quite impressed with how well LE works on it otherwise, having 10-bit HDR would make it perfect imo. I'll keep an eye out then and see if there is anything I can do to contribute. Thanks for the awesome work you guys are doing!

When playing HDR content on the Rock Pi 4 it triggers HDR on my Sony Bravia AG8 but there seems to be something wrong with the colorspace. The colors look washed out and there is visible banding. The TV seems to interpret the signal as BT.709 and limited range (auto setting). Manually changing the colorspace to BT.2020 on the tv doesn't fix the banding. Setting the range to full produces incorrect black levels.
I tried using a Raspberry Pi 4 with an identical setup, there the colors look correct with no banding. In this case the auto setting on the TV interprets the signal as BT.2020 and limited range.
Not sure if it matters, but when checking modetest on the Rock Pi there doesn't seem to be any colorspace property
