How much to repair an iPhone 11 true depth camera

According to iPhone Repair & Service, the estimated cost would be $399 without Apple Care, and $99 with Apple Care. The price for the actual replacement though I am not sure of. Consulting with an AASP (Apple Authorised Service Provider) or an Apple Store they'll provide the exact price.

Apple lists repairs for the Back Camera, but the Front Camera is not listed. I checked under "Other" , but camera repair was not listed. The cost of "Other" is about $400 U.S. without AppleCare.

So, it is not really clear yet as to whether Apple really offers repairs for the Back Camera, or whether you will be offered another Refurbished replacement phone at a reduced cost.

Best to check at the Apple Store or at an Apple authorized service shop.
