I believe WB and lens corrections are implemented differently in RT. @jdc would know more about WB.
I would advise against applying lens corrections because they have a greater impact than you might realize from visual inspection alone.
Aside One thought just came to mind. I don’t use dt but run it when curious about something or when I want to help somebody. I noticed that dt’s controls are quite conservative compared to RT. RT’s modules tend to have more of an effect on the image. It is more of a feeling than anything.
