Help, support CPM build

Anyone having handshake issues with Display-LED Dolby Vision? My Dolby Vision symbol triggers twice on TV (haven’t tried Profile 7 but have tested with a few 8.1) and my TV has inaccessible DV settings (can’t change Clarity or Brightness…) I’ve never seen it before.

Player-LED seemingly works but the color is not very vibrant and the blacks aren’t accurately deep.

I installed 21.1.1-Omega and updated to the latest CPM.

Apologies if this is the wrong forum.

My TV is a Hisense 100U8K.
