    Hi there,

    I have a Subtractive Baked Lightmap set up for my scenes.

    1) Android build active - it looks fine and doesnt have any dots on surfaces

    2) iOS build all the surfaces are covered with some dots:



    I have URP and those settings:



    What can cause such a graphical artifact on iOS? Any ideas?

    Might be the compression used on iOS. You can verify that by disabling "Compress Lightmaps", although a 4K lightmap size is quite large, you may want to reduce that.
    If it's the compression, you can select the lightmap and set a specific compression scheme for the lightmaps on iOS.
