Grey bars on Fold split screen

[Psychotik 1]

Hello, 

On Android version 3.4.14 on the samsung fold 5. When using the app on split screen there is some very ugly and distracting grey bars around the video. I was wondering if it could be changed to full black. In other apps it works like youtube it works properly. I'll attach 2 examples: one emby vs youtube.

Hi, interestingly someone reported something similar on ChromeOS, but the Emby app doesn't use gray anywhere. Anyway we're looking into where that's coming from.
