I think Max's 1S only appeared with Strike Packs in Macross 7, in the "Minmay Story" where they were talking about the history of Max and Miria relationship. They had a short clip of Max's 1S fighting against the Q-Rau, this time in space. So we get to see a Strike Valkyrie 1S Max.
While in DYRL the 1S was shown to have a black heat shield, I'm not sure if the Skull logos in the Strike Packs are black are blue since they were never shown and is probably left to fans.
While I like the blue Skull logo on the Strike Packs more, I think black Skull logos also fit more if you want consistency with the heat shield color.
