I would suggest manufacturers are attempting to 'complete' the information obtained at 0.6 (etc) using software solutions.

I don't know of any way to do that. It's just superposition in the frequency domain that makes this stuff look weird.

The way that comes to mind is to continue the patterns and colours known within Nyquist and extend/alter according to the partial information showing up beyond Nyquist.
