To rule it out have you tried turning off all of the pic enhancements, motion interpolation etc ?
yup. Even set tv to "Filmmaker" picture mode that disables all processing.
But, even with all the things on... again, no flickering in other apps.
For now, i am just going to set Channels DVR app Deinterlacer to Linear and not Hardware. That resolves the flickering.
Unless Channels devs want to further investigate this issue with me, make testflight builds with different deinterlacers or something... but, seems to be a edge case as it only with Samsung QLED Mini-LED type tv that seems to have this issue...

Recent trying out of Channels for use with local media Library has me re-visiting this topic.
Here is a more recent example. Notice the background flickering with the Hardware example.
(worst flickering is about at 30secs)
File is progressive. But this happens with interlaced files as well, as well as with live tv and dvr recordings.
(note! SPOILER . This is a short clip, no audio, from the Series Finale of Start Trek Discovery. )
Hardware
Linear
Weirdly, flicker does not happen with my Mythbusters episodes files, or is extremely rare or minimal, i do not notice it.
Please submit diagnostics from the app after playing with the Hardware setting.
Any chance your Apple TV has HDR “on” all the time? Only ask as Samsung doesn’t support Dolby vision, so it meshes with why this would be isolated
No. Is SDR. I rarely use HDR, and when i do, it auto switches to HDR output mode.
The example files being played are SDR source files too.
Also, seems this flickering issue when using Hardware does not happen when playing HDR content.
Submitted.
I do have the DVR recording of Stargate Atlantis episode that i used as an example several posts back, somewhere.... That clip in the dark cave thing with them walking in frame, where it flashes Rainbow like, is the worst i have ever seen it do it. That is a lower quality source though, Pluto tv channels recording.
Any insight into this?
Started to watch episodes of The Acolyte and on Hardware, the flicking is present.
Changed to Linear and it is gone 99% of the time.
I just submitted diags from the app, once when playing 1 min with Hardware, and then 1 min of Linear.
And just to add, i downloaded the same episode in HDR and seems that there is not flicking with Hardware setting, when playing HDR content. (I also confirmed this by playing SDR and HDR 2160p episodes of the new Season of Criminal Minds Evolution. With SDR, flicker alot, especially in dark scenes with grey shading etc. HDR, no flickering.)
I suspect that some of this is caused by my Samsung TV... however its firmware or algorithms etc is displaying the picture. Despite the fact that i almost never have seen this flicking issue when using Infuse, or when using Linear setting in Channels.
Recently, i have been noticing less flicker in content i been watching.
I could not even watch Live tv channels, like the Star Trek Pluto tv channels, while using Hardware, due to the flickering being so bad.
I even copied back the recording clip of that episode of Stargate Atlantis, that had a crap ton of flickering when using Hardware. Playing back now, in Channels, there was no flicker at all.
I then forced a reboot of my Samsung TV (via hold down Power button on the remote).
After reboot, there was some minor flicker in the same clip, and on the Live TV channels, but still nowhere near as bad as it was in the past.
So.. not sure what changed in Channels beta apps in the last 27 days or so, but something in it has greatly reduced flickering issues in my environment. (my Tv's firmware or picture settings have not changed)
This "issue" appears to be resolved, for the time being.
