I'm experiencing the same issues with the X5. I shoot in manual mode w/ DLOG enabled.
While I utilize ETTR all the time for raw image formats (when shooting time-lapse) on non DJI gear, you have to be careful with the highly compressed 60mbps h264 4k video on the Inspire/Phantom3Pro because you cannot easily recover highlights in post. I find a balance between shadows/highlights on the histogram within GO when shooting high contrast scenes. This achieves great results (despite the tiny sensor size) on my P3Pro. On the X5, I shoot in the same way but have been experiencing all the nasty, purple posterization and blotchiness in the shadows and midtones. Using ETTR will eventually fix the problem in the shadows, but then you're dealing with blown out highlights.
I was convinced that the sensor on the x5 I have been using might be a lemon, so this is an interesting post to see another user having the same issue. It's embarrassing when my P3Pro can produce a better image (excluding the longer focal legnth on the x5 which is desirable in my opinion) during a sunrise/sunset scenario where I'm pushing the sensor to its dynamic range limit. Based on technical specs, the x5 should be far superior to the P3Pro. Why isn't it?!?
Here are two X5 examples of the issue (4K video frames, no post work):Click to enlarge.
#1 Look at the trees in the shadow -- lower, middle.
#2 Look at the trees in the distance and also the foreground in the lower left corner.
Now two Phantom 3 Pro (4K video frames, DLOG, 1/50th, no post work) - No purple posterization issues:
