Just curious: The previews always get dimmer (and saves that way) when the global brightness slider or the brightness limit setting is reduced.
However, I’m almost always using those settings for the particulars of my power management or viewing environment, and it’s never been valuable to me for the previews themselves to be dimmer as a result.
Is it possibly because the stream of pixel color data sent back to the browser incorporates it, so it would need to be intentionally un-done by re-scaling up the brightness, and potentially lose resolution in the process?
