I have used the Vivid color profile on my Phantom 4 Pro quite a lot for casual videos.  I see now, that Vivid has disappeared as a choice, and that there is a new Blockbuster profile in DJI Go 4 (as well as Litchi). I'm not familiar with what Blockbuster is achieving, but it certainly does not behave the same as Vivid did. So, how do you achieve a similar profile as Vivid?

I suppose it's possible that my camera has gone wonky, but I thought I'd ask the above question first.

The vivid has been removed for now, and I would recommend you to use the Warm effect.
