Do the following:

Download the IOS file with the TAR extension (and not the BIN)

Run the following commands:

del /f /r flash1:flash*
archive download /overwrite tftp://<TFTP_IP_ADDRESS>/IOS_filename.tar

That is it.
The 2nd command instructs the system to do the following:

Verify if the IOS file is compatible with the system. If the file is compatible, proceed to #2, if not, stop the process.
Unpacks the new IOS to all the switch members in the stack.
Deletes the old IOS from all the stack members.
Change the boot variable string to point to the new IOS file.
Perform a quick HASH check to make sure the BIN file is not corrupted during the unpacking stage.

One command does all of that. Does the "copy tftp: flash:" do all of those? Especially #1 & #4, it doesn't.
