Low frame size from internal player

Hi,

Is there a way to force the internal video player to use a high frame size?

When recording, from Prime, if I use an external instance of Chrome, then the framerate will be 1900x1080 where that is available. And I see the option in the video settings to use "Best - around 6 Gb per hour".

When using the internal player, it is as if the website detects it as a mobile device, and so the maximum quality I can get under "Best" is around 1 gig per hour, and the frame size is often something like 900x400.
