            Bug ID: 244845
           Summary: [iOS] screen.colorDepth reports incorrect value
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org

On iOS, screen.colorDepth is hard-coded to return 32 (see https://github.com/WebKit/WebKit/blob/main/Source/WebCore/platform/ios/PlatformScreenIOS.mm#L52).

However, according to the spec (https://drafts.csswg.org/cssom-view/#dom-screen-colordepth), the return value is meant to be the number of bits allocated to colors, excluding the alpha channel, so 32 seems generally incorrect.
