Does it come with any HDR to SDR capabilities ? cause stripping off 2 bits means that tone mapping will cause a lot of banding as it won't have the expected precision. I'm simply trying to make up the big portrait so we don't just offer yet another foot gun. But perhaps its fine to offer this, its just that we don't have a mechanism to report which pixel format in the selection will cause data lost.

No it just to enable post-processor capabilities like we have already for G2/HEVC. Since it is a post-processor pixel format it will be enumerated after V4L2_PIX_FMT_NV15_4L4 so it will update to userland to decide to use it or not.
