Since 1.6, the transfer function for BT2020 has been changed from BT709 to BT2020_12. It's the same function, but with more precision. As a side effect, the V4L2 colorpsace didn't match GStreamer colorspace. When GStreamer ended up making a guess, it would not match anything supported by V4L2 anymore. This this by using BT2020_12 for BT2020 colorspace and BT2020 transfer function in replacement of BT709 whenever a 4K resolution is detected.
