They've got the complete set on the Superman I-IV blu-ray set. Any idea if they're the same transfers/masters?

On the Superman 1-4 BD set, the shorts are the same 480i transfers as on the WB "Max Fleischer's Superman, 1941-1942" DVD set. Aside from minor audio issues, it's the best one out there, and looks superb even upscaled to 1080i. Going by the color bleeding and remaining video artifacts on Gaiam's "botchered" BD release, it seems to use the same masters as this release (http://www.amazon.com/Superman-Lost-Episodes-Animated/dp/1572524537/ref=sr_1_1?s=movies-tv&ie=UTF8&qid=1438733291&sr=1-1&keywords=superman+winstar)
