That makes sense; I should revise what I said earlier--after comparing all the various screenshots for the home video versions, the matte painting is all the same. In other words, the Moth3r/Citizen transfer simply provided the best point of comparison because they are the clearest 1981. Bottom line: all home video versions have been the same and they are all the same as the 1977 except the composite is different--the 1977 version had distortion, while the 1981 re-composite had a new starfield and no distortion, and either the same Tatooine as 1977 or a new composite of it as well; I'll have to take a further look at that and the small moon.
