Grainy TIF at Low Zoom Levels When Exporting Aerial Imagery from SID

I am building a Web App for a municipal government. The county recently commissioned some high res aerial imagery and the municipality wants this included as a custom basemap. They've given the imagery to me as a series of SID files. To make a tile package, first I need to mosaic the SIDs, clip them to be just around the municipality's borders, and then export as a single TIF.


When I did this, the resulting TIF comes out weirdly grainy when I am zoomed out, even though it it still high resolution at greater zoom levels. It's not an issue with stretch type, resampling, etc because I have the same settings applied to both layers.
