WICColorContextUninitialized is returned by IWICColorContext->GetType

[ByteYIFFF]

Hello, I want to get the icc information in tiff format through wic, however, I found that WICColorContextUninitialized is returned by IWICColorContext->GetType when I decode to get an image frame. At the same time, my code can get the icc information in jpeg format.
What is the difference in the way of obtaining icc information between tiff and jpeg.
