ByteArray placeholder Coil-compose

[Fra078]

A library exposes an image https link and a low-res placeholder represented by a ByteArray. During the download of the image I need to show the placeholder. Currently I'm creating an asyncImageLoader with as placeholder parameter a new asyncImageLoader with the byte Array as argument. But I'm worrying about the performance cost to instantiate 2 asyncImagePainters for every element in a list. So, there is a better way to do it?
