Thanks for your answer.

I've tried the fllowing:
stream.Length = 0;
stream.Capacity = 0;


But I coudn't access those properties from a MemoryStream.
So I've actually followed your advice and developped my own Stream implementation. This allowed to track what was called at least. This unfortunately didn't solve the problem. I could only see that the Close() function was called, that I could clear the Buffer that was stored there. However the finalized never gets called, giving a hint that the parent ImageSource or Image never get freed either.
Moreover, using my own Stream prevents me from freezing the ImageSource (I don't know why).

Here follows the implementation of the Stream I used:
public class ManagedMemoryStream : Stream
 {
     private int Id;
     private static int Index = 0;
     private static int Counter = 0;

     private byte[]? Buffer;

     public override bool CanRead => true;

     public override bool CanSeek => false;

     public override bool CanWrite => false;

     public override long Length => _Length;
     private long _Length;

     public override long Position { get; set; }

     public override void Close()
     {
         System.Diagnostics.Debug.WriteLine($"ManagedMemoryStream: Close {Id} / {Counter}");
         base.Close();
         Dispose(true);
         Buffer = null;
     }

     public ManagedMemoryStream(byte[] buffer)
     {
         Id = Index++;
         System.Diagnostics.Debug.WriteLine($"ManagedMemoryStream: Construct {Id} / {++Counter}");

         Buffer = buffer;
         _Length = Buffer.Length;

     }


     ~ManagedMemoryStream()
     {
         System.Diagnostics.Debug.WriteLine($"ManagedMemoryStream: Finalize {Id} / {--Counter}");
         Dispose(false);
     }

     public override void Flush()
     {
         System.Diagnostics.Debug.WriteLine($"ManagedMemoryStream: Flush {Id} / {Counter}");
     }

     public override int Read(byte[] buffer, int offset, int count)
     {
         //System.Diagnostics.Debug.WriteLine($"ManagedMemoryStream: Read {Id}, {offset}, {count} / {Counter}");
         if (count == 0 || Buffer is null) return 0;
         int remaining = (int)(Buffer.Length - Position);
         if (count > remaining) count = remaining;

         Array.Copy(Buffer, Position, buffer, offset, count);
         Position += count;
         _Length -= count;

         return count;
     }

     public override long Seek(long offset, SeekOrigin origin)
     {
         throw new NotImplementedException();
     }

     public override void SetLength(long value)
     {
         throw new InvalidOperationException();
     }

     public override void Write(byte[] buffer, int offset, int count)
     {
         throw new InvalidOperationException();
     }
 }
