AppleTV 4K screen randomly turns black for 1-2 seconds

Hello, I own an appleTV 4K (latest gen) and I have been experiencing a weird problem for the past year. When streaming content (happening on multiple apps), the image/screen will randomly turn black for 1-2 seconds here and there. The show continues normally after that but it can happen twice a day or twice a week, sometimes after many hours of usage. (not just when starting a show)

Restarting the box, factory reset it and changing multiples times the HDMI cable (2.1 compatible) didn't solve the issue. I also tried all my HDMI inputs on my TV and no luck either. So it has to be appleTV related since I never experience this on my TV native apps and my google TV streamer.

Anybody else having this? Wonder if it's hardware of more software bug.

PS. Changing matching frame rate settings (on and off) didn't solve it either.

Thanks for your help.
