I am getting a green strip at bottom part of my TV screen.

TV Model : Vu Premium Android with Cricket Mode(43-OA)

There are different scenarios to this.

1.Keeping content at Automatic(upto 4k)+ always HDR : Green Bottom Strip on complete Fire TV Stick, even on playing non HD movie getting a green strip, even on Fire TV Stick 4k homepage as in the image.

2.Keeping content at Automatic(upto 4k)+adaptive HDR : Green Bottom Strip appearing on playing any Dolby Vision content on Fire TV Stick 4K from Netflix or Prime Video.

Tried playing Dolby Vision content from pre installed Netflix app on TV and it is working flawlessly.

Switched in a PS4 Pro and even that played content fine without any issues.

I contacted the TV support and they are not sure about the issue as they are claiming that it is a software issue but they need to check it, and then upgrade and downgrade SW, they already tried once but failed

Have already tried factory resetting Fire Stick, Updating it to latest patch, factory resetting the TV, changing HDMI port, changing HDMI from Standard to Enhanced on TV settings but nothing worked.

Even ordered a replacement for Fire TV Stick to confirm where the issue is.

Was using an older model of same TV that was on January 2019 Security Patch and it was working fine with Fire TV Stick 4k, but that had issues with Wifi so ordered a replacement, but this new variant is on June 2019 patch
