Display Channels for Images in 3D Viewport

The 'Display Channels' dropdown in the Image Editor is an excellent feature, as it allows the user to isolate specific color channels for reference. I would like to see this feature brought to the 3D Viewport as a setting in the Image Data Properties, as seen below:

This would replace the 'Use Alpha' checkbox, as the Color and Alpha option would include alpha, and the Color option would not. This dropdown would include the following options:

• Color and Alpha
• Color
• Alpha
• R
• G
• B

These are the same options available in the Image Editor, and they would behave the same way.

This would be useful for users who need to isolate a specific channel in the 3D viewport when using that channel as a reference for modeling, pixel sampling, etc.
