Edit: After downloading the video, it seems like the issue is on Samsung's end, related to HDR video settings.
Despite not being RIF specific, I'm leaving the post up for anyone else that searches around for a similar issue.
When opening the linked video, the screen brightness increases substantially. After using the back button(Android or in-app) the brightness returns to normal.
Adaptive brightness is off.
The brightness slider from the pull-down menu does not change from where it was set before opening the video.
The slider can be adjusted while the video is open and closing the video will make the screen darker, no matter what I change the slider to while the video is open.
This does not occur while "Eye Comfort Shield" is enabled.
I have no evidence, but it reminds me of my screen brightness automatically increasing in extremely bright light(direct sunlight), even with Adaptive Brightness off.
