1.7.0 SLP 2.6 don't export BT709 color space

Win11 / RTX5060Ti

My source is AVC YUV420 BT.709. I set the output AVC. With SLP I don’t have BT.709 in the export file, even if I set it hard in Project setting Color space on BT709.

For review, can you send the logs for this issue since its specific to a color profile and source file that you are using?

BTW, look why I must wait 6 minutes before SLP starts working. In 1.6 it was few seconds.
