Still using bilinear transform?

Hello,

I'm working with an ADAU1452 and am just wondering if Sigma Studio is still using bilinear transform function for filters like LR4? It would be unfortunate if this were still the case due to the phase issues. It's an otherwise very impressive piece of software.

Thank you,
