C7LookupTable with HDR video

[BRIKSING]

Hello! Thank you for your framework!

I tried to add HDR video support in my editing app for export, but colors is wrong sometimes
Editing video with no HDR edit is great.
I use C7Collector like in demo, but I convert CVPixelBuffer to MTLTexture and back for custom compositor because it's working faster.

If you try to use neutral lookup table, it seems like the colors are faded.

Here lookup table and HDR video for example with screens

Screenshot with correct colors without using HDR

Thanks in advance!

P.S. Try to use CIColorCube filter but there were memory leak while exporting with this filter.
