just incase anyone has this issue in the future
youtube definitely shifts gamma…
the fix i used for this to get the results close for this after a lot of experimenting is to up the saturation in premiere clip by clip about +10%
then from the youtube “enhancements” tab which re-renders through youtube servers… to up the “fill light” +1, and then up the “contrast” +1
there was nothing i could do in premiere only to duplicate these results, i made about 15 drafts. this technique ive mentioned gave the best results
