My LG 86un85006la is supposed to have a decoder for:

HEVC (H.265): 4K@60p with 10 Bit

LG UN85 86 inch 4K Smart UHD TV | LG UK

With the following video stream:

videoStream: {
  "id": 291862,
  "streamType": 1,
  "default": true,
  "codec": "h264",
  "index": 0,
  "bitrate": 21795,
  "bitDepth": 10,
  "chromaLocation": "left",
  "chromaSubsampling": "4:2:0",
  "codedHeight": 1600,
  "codedWidth": 3840,
  "frameRate": 23.97599983215332,
  "hasScalingMatrix": false,
  "height": 1600,
  "level": 51,
  "profile": "high 10",
  "refFrames": 4,
  "scanType": "progressive",
  "title": "*********",
  "width": 3840,
  "displayTitle": "4K (H.264 High 10)",
  "extendedDisplayTitle": "********"
}

I receive the following Info, resulting in unwanted transcoding:

Jul 14, 2021 21:09:40.093 [***] INFO - [Plex for LG] [***]     Cannot direct play with protocol: http, codec: h264. Reason: Video stream exceeded a max bit depth of 8

Am I missing something or is there something wrong?

The TV probably does not support 10-bit H.264 video.

Edit: From webOS TV Developer site:

webOS 6.0 & 5.0 supported H.264 formats:
H.264 3840x2160@30P BP/MP/HP@L5.1 Maximum 50Mbps

H.264 High10 is not listed as a supported profile, only Baseline, Main, and High.
