How to reproduce:
1. Create a new Unity project and install the Visual Effect Graph package
2. In the Project window, right-click -> Create -> Visual Effects -> HLSL File
3. Confirm the name and observe the Asset icon
Expected results: The icon is high resolution
Actual results: The icon is low resolution
Reproducible with: 6000.0.74f1, 6000.3.14f1, 6000.4.6f1, 6000.5.0b7, 6000.6.0a4
Reproducible on: macOS Tahoe 26 (M1)
Not reproducible on: No other environment tested
Note: Due to the fact that currently there are two different icons on creation, it is easy to compare that the one after the name confirmation is lower resolution
