Hmm, I've not heard of that restriction, but it's pretty easy to test...

...I did a test with 3 spheres with different reflection values, and the camera
inside a black sphere with transmit 0.1. The reflections showed all of the
details on the HDR image, with no flattening of colours until they hit full
white. So I can't find any limitation on the brightness of reflections:

That was using ML pov, but the same test scene replaced with a very brightly
coloured sky (rgb 20) in standard POV 3.5 also showed no capping of reflections.
