Learning about Dolby Vision and CoreELEC development

As I haven’t received a reply to my question on this thread, I hope this is the right thread to post in.

I installed CE Amlogic-ng 21.3 on my Odroid n2+ (SD card).
All Dolby Vision contents played are reported as HDR by my LG OLED TV, unlike CE, which reports DV. I did not try Profile 5.

Before posting logs, my question is: Is CE 21.3 able to play DV content on N2+? . Does it exclude profiles?

Thanks
