To master color in DT you can go to this epic thread …
and check out the content from the YT channel that it is centered around… @s7habo has an amazing library of content that is especially helpful in demonstrating how edits are done in DT which as you noted doesn’t do much with the image out of the gate and so often new users see the colors as dull… In reality most programs have added a profile which adds tone and color out of the gate. Even in RT if you change the model of the curve used the resulting color is very different. There are many nuances like that in DT that can dramatically influence color.
Its a long thread and the earlier stuff is now using a much older version of DT but there is abundant information in there…
