I always thought it would be cool if passthrough videos' image settings automatically changed based on my room's lighting. However, Meta didn't offer devs access to the passthrough feed, so it would've been impossible until now. It would be especially useful at night, since my warm room lights don't match the bright white studio lights of the recording sets. Manually changing the DeoVR image settings can help make the contrast less noticeable, but it's not enough, and it's time consuming
