It kind of depends on who at Steam is reviewing your game and when it got flagged. If it already got noticed for the old content then they are going to be more harsh on reviewing any changes you make. I'm not a developer personally but know someone with numerous titles on Steam and has had trouble with them over some games as well and this is just what I've picked up from those dialogues. If you think Oppai-Man is making even more harsh changes weeks later for no reason then go ahead but it's pretty clear that the changes they already made didn't pass checks and even further changes needed to be made. What reason would they make even more drastic changes otherwise?
I don't know, considering the types of games that are on steam I have a hard time believing that the room color and stuff like that, would be an issue. I think they probably saw the lines where the mc says that she is too young and they told the dev to remove those types of references and he just when overboard with it.
Especially when you consider the fact that steam is a plaform for video games. If you work for steam I doubt that you are unfamiliar with the whole gamer/streamer girl look. I just don't see the reason why they would tell the dev to remove those things, but I could be completely wrong.
