ImageryLayer interpolation with a renderer

Hello,

My javascript map properly display an imageryLayer coming from an image server:

As you can see, the layer in displayed with bilinear interpoaltion as asked in my code:

let layerTMOY_QUOT = new ImageryLayer({ url: URL_TMOY_QUOT, interpolation: "bilinear" }); map.add(layerTMOY_QUOT);

Now if I add a renderer to the imagery layer, the dsplayed image is no longer interpolated:

You can see all the individual pixels. It seems that the interpolation properties is now ignored despite what I wrote in my code:

let layerTMOY_QUOT = new ImageryLayer({ url: URL_TMOY_QUOT, renderer: rendererTemperature, interpolation: "bilinear", });

How can I use both a renderer and interpolation of the displayed pixels?

EDIT: Here is the code for the renderer,in case it could be useful :

let rendererTemperature = new RasterStretchRenderer({ statistics: [[-50, 40, 0, 0]], stretchType: "min-max", colorRamp: new MultipartColorRamp({ colorRamps: [ { algorithm: "cie-lab", fromColor: new Color([255, 0, 192, 255]), toColor: new Color([255, 128, 255, 255]) }, { algorithm: "cie-lab", fromColor: new Color([255, 128, 255, 255]), toColor: new Color([208, 254, 254, 255]) }, { algorithm: "cie-lab", fromColor: new Color([208, 254, 254, 255]), toColor: new Color([104, 127, 178, 255]) }, ] }) });

Ok I found a solution. Forcing the format of the ImageryLayer to be "lerc" show the images as interpolated again:

let layerTMOY_QUOT = new ImageryLayer({ url: URL_TMOY_QUOT, renderer: rendererTemperature, format: "lerc", interpolation: "bilinear" });
