I was having the same issue on my Note 10 but recently found out how to solve it. You need to open the google play books app or download it if you dont already have it (I know that sounds weird and random but it works!) Then select a book to read. If you don't already have any books just download a free sample. When you are reading a book, click on the double A's that look like this Aa. Then click on the tone tab, click on the settings icon next to night light, schedule should be set to none, and under intensity select turn off now. After that my gallery has not changed to that yellowish color. Hope this helps you!
