Yes, I stumbled on it last night – settings>display>contrast and colour. There is a slider that adjusts from warm to cool tones. I moved my slider right the way over to freezing cold. It has improved, however, it is still not quite as brilliant white as my Xiaomi Note 4. If you looked at my Mi Max 2 on it’s own, with the setting all the way over to cold, it would look quite acceptable and not noticeable. However, if I put a Note 4 right next to it, I can still see a small difference
