Chromium browsers not upscaling, only stretching on Disney+

[MrMar]

Not sure if it's just me, but it seems there might be an issue where in chromium browsers it is only stretching and not upscaling on Disney+.
I've only tested it on Windows 11 with Disney+ and YouTube, with Brave and Edge. YouTube is upscaling on both Brave and Edge, but when watching Disney+ it is only stretching. However when tested with Firefox, Disney+ will upscale and/or stretch (as expected)

Edit: This seems to be related to this If so, please hide this post. I should have searched better...
