Don't believe there's a regression here, but would be good to verify everything is working as intended still after the scene-alpha refactors, no accidental swapped inputs or incorrect sampling. AA did have a sharpness improvement and is the likely culprit but that's intentional. Should be quick to verify and close the ticket if everything looks good.

Please reply to the UDN if if everything is fine or you find a problem, thanks.

Steps to Reproduce

Render a frame through Sequencer using the quality settings mentioned in the UDN ticket or create a scene with circle depth of field active. Results should match those in 4.14.

Or the UDN also have a cut down version of their project to repro quiet easily in the level sequence of its unique's level.
