Because you gave the context clues of M4 chip and OLED screen and $1200 repair cost, this means you somehow snagged an iPad Pro 13” with the cellular modem for $500, which is way below market value.

The current version of this model of iPad purchased brand new is $1700.

In other words, this is the highest end iPad available. Any other lower spec model reduces the repair cost lower than what you were quoted.
