I don't think it is lost, just personally I feel like I've said everything I had to say about the subject. The feedback is here and hopefully received, so adding even a thousand more replies won't make them work any faster if they wish to make the colors and lighting realistic and immersive as they were prior to Patch 8. Nor will it make them change their mind if they do not.
Personally I do not think this is the final state of how the game is going to look due to plenty of inconsistencies in graphic quality which has severely degraded since Patch 8, so I think if they are making any changes and improvements it will be seen with Content Update #9 or the update after when they do the optimizations. Patch 8 broke many things since Patch 7, so this might just be yet another victim of feature implementations.
