Most brake fluids are coloured differently so you can detect when the new fluid has passed its way through all the lines.

That in turn will indicate you have changed your brake fluid - nothing more. Provided you stick to brake fluids that are compatible with other fluids (there are some that can't be mixed with other fluids) you are doing nothing wrong at all. Upgraded brake fluid itself doesn't put any additional strain or wear on any parts. It just has a higher wet/dry boiling point. That fact the OEM fluid boils early is not a reflection of safety margins, etc... just BMW saving themselves a buck as in everyday driving boiling the fluid is quite hard.

Hope that helps
