I don't know that Mi A1 is using Amoled or IPS, but yes, some of them have burned in and have shadow over there.

Also for the Redmi version. But my father's Mi A1 is still ok this time.

AMOLED displays used only in very expensive flasghip phones.
Midrange phones use IPS panel and the cheapest phones use only TN panel.
Yes, the Mi A1 use IPS, and my LeEco phone has IPS too. I like IPS mote than AMOLED, because it has better white colors, but AMOLED has better deep black colors. And for browsing the net you watch a lot of white.
