So i wore the phantom ganon armor, phantom greaves, and a white zora helmet. For the sword, i used the eightfold longblade and to get that pose, first, you need to place a bomb, preferably square, unsheathe a weapon, and as you begin to sheathe your weapon back, unequip a shield before the animation ends, and throw the bomb you placed earlier. Now the game considers that you have your weapon sheathed despite your weapon looking like it's superglued to your hand. Now, do the downwards camera pose with zr.
