SOLVED: Video cropped at the top and bottom on Google TV Jellyfin player

[furythestunner]

Hello,

I have an issue with aspect ratios and cropping / black bars.
I am running Jellyfin server on my PC, and trying to watch content on my TCL C835 TV (4k - 3840x2160 resolution) it has native Google TV.
The content I'm trying to watch is 3840x1600 and it shows up perfect directly on my PC (VLC player) and when watching it from the browser:

If I play it on the TV the top and bottom are chopped off (see heads):

I tried turning off Overscan on the TV, tried all the different aspect ratio combinations of both TV settings and Jellyfin player. It either just zoomed in more or chopped off content from left and right.
If I enable external player in Jellyfin settings and play it in the TV's default media player it shows up fine - this leads me to think this is a Jellyfin TV app  internal player issue.

Looking forward to some help what could be causing this.
