Extracted raster is blurrier than source

ArcGIS Pro 3.3.1

I've brought this raster data into Pro by clicking the ArcMap link to download a .LYR file.

I'm using the DRA option in the Ribbon > Imagery > Raster Layer tab.

The raster .LYR file looks like this in Pro. The pixels are crisp.

But when I export my subject area using Clip Raster or Export Raster, the pixels are blurry (DRA is used here as well).

Why are the pixels blurry in the raster export?

I noticed that the Resampling Type was set to Nearest Neighbor in the source data.

But in the exported raster, the default Resampling Type was set to Bilinear.

So, I changed the Resampling Type in the export to Nearest Neighbor. That made the pixels less blurry.

This is the type of thing that validates wanting a standalone ProArcCatalog app that will allow you to do data things and view data without ANY symbology, transformation, etc. 

I wish I could turn off all the '!help' Pro offers by automatically applying filters, styles, transformations, etc, etc. Give me Nothing Mode now!!! LOL.
