Hello,
I realized that the Sceneform Camera output is more saturated / brighter than the ARCore Unity counterpart.
The Unity camera looks more realistic like normal camera whereas the Sceneform one looks like one with a filter and lesser details.
Is there some way to avoid the saturated camera output?
(Not a very good sample image, sorry about that)

Unity:

We can confirm this difference. We will update with a workaround or update.
This issue has been fixed internally.
This is now fixed in Sceneform 1.4.
