Appearance: Non-focused window in Light theme preview looks too much like dark theme
The “Light theme” preview image currently shows both Light and Dark windows within the same desktop. This is a bit confusing and was noted by one of the youtubers reviewing Gnome 42 as well. Based on this discussion, this is done to show that background apps are slightly dimmer. In my experience, they certainly don't look this dark and the preview makes it look like a mix of light and dark theme windows. With the Light theme, the window colour is essentially unchanged with the only difference I see between the focussed/unfocussed windows is that focussed windows have a darket the top bar.
I would propose to update the preview as shown below to more closely match the default colour scheme.
