I think when I did the test I had .240 firmware. Now I have .330 and I have no plans to upgrade it at this moment.I think he shot that with an order version of the fw. The latest version .300 fixed the WB and tint issues (or at least it’s very good in AWB). They just need to make the AWB setting match the same tint when manually setting the temp to same value.
Here is one of my latest videos that filmed with i2 x5s (firmware .330) half shot in dng 5.2k and half prores 422
