This video stutters on Apple TV 4K but not on MacOS Plex app?

Hello, can anyone identify why this video stutters on Apple TV but not on MacOS Plex app?

Server Version#: Version 1.25.2.5319
Player Version#: Apple TV 7.26 (1744)

This video plays fine for a while and then starts to stutter after a few minutes. If I scrub back ten seconds, then it is fine again for a few minutes.

Video does not appear to be DolbyVision but it is HDR. No transcoding is indicated in the server.

Other HDR videos no not have this problem other than Dolby Vision.

Logs attached.

Any ideas? Can I provide more information?

From what i have read, 1080p main10 HEVC have this problem.
4k files with main10 HEVC should play fine.

Plex dev should fix this issue, i believe they think it doens’t exist but i had this problem too today. That’s why i’m here.
