This is just a quick reskin of the Deathclaw models that changes their color from the new greenish-brown with a pale underbelly to a darker brown with a darker underbelly, to try and more closely match the color scheme of the Deathclaws from the earlier games.
To make sure it shows up in-game, be sure to change your “Fallout4.ini” file to load loose textures: Replace the line “sResourceDataDirsFinal=STRINGS\” with “sResourceDataDirsFinal=STRINGS\, TEXTURES\”.
