Black horizontal lines on iMac M1 Ventura

Hello, I see black horizontal lines on display iMac M1 2021 Ventura ( 18 months from purchase , 6 months out of warranty). Factory reset done but issue persists. Its out of warranty so have to bear the massive repair expenses of changing the display but I also hear that Apple conducts repair camps if the issue is pervasive and related to product ( as against usage). Are we expecting any repair camps for M1s ? Its hard to believe that a top of the line product like M1 has a life of only 18 months.
