Got my copy [of season 1] last week, can confirm it's the Toei remaster. And finally Viz Media stopped doing stupid thing like messing up the color like they did with the Sailor Stars releases.
What did Viz do with the Stars colors? I thought it was confirmed that Stars is the same as the Japanese BD?
They did the wrong color matrix transformation. Here's some background info, SD/DVD video uses the Rec601 color matrix while HD video uses Rec709, the difference between the two are in the red and green color. Normally when we're upscaling a SD video to HD, we'll also need to do a Rec601 to Rec709 conversion to the color.
When Viz got the remaster from Japan, it was already in HD, which means Japan already did the 601->709 conversion. There was really nothing needed to do. But Viz took it and stupidly did another 601-709 conversion again, which messed up the color.
Here's a comparison shot:
