Thank you for reporting a bug to Unity. After reviewing the behavior, we've confirmed it aligns with the current design and intended use of the feature. We understand this may differ from your expectations or workflow. We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.

How to reproduce:
1. Create a new 2D Unity project
2. Go to Window -> Package Management -> Package Manager
3. Go to 2D Common -> Samples -> Import
4. Close the project and upgrade it
5. Observe the Console

Expected results: No warnings are thrown
Actual results: Around 50 different warnings are thrown

Reproducible with: 6000.0.73f1, 6000.3.14f1, 6000.4.4f1, 6000.5.0b5, 6000.6.0a3

Reproducible on: macOS Tahoe 26 (M1), Ubuntu 24
Not reproducible on: No other environment tested

Note: The warnings are thrown even when the project has a small version update (e.g. from 6000.6.0a3 to 6000.6.0a4)

Warning sample:
Source Texture (Assets/Samples/2D Common/14.0.0/Sprite Atlas Samples/BuiltInVariant/Sprites/Sprite_Fire_Additive.png) of Sprite (Sprite_Fire_Additive_1) is using compressed format. To ensure no loss in source pixel details when packing to SpriteAtlas, please use uncompressed format in TextureImporter.
