FireTV v1 + Krypton Audio Question

I am trying to keep it simple. I searched through all of the various threads. I just don’t know much about Android and know even less about all of he various versions so I have struggled to find a clear answer to this question. I think the answer is “no”.

If I update my FireTV v1 to Krypton, will I lose DTS passthrough? Will I lose surround sound?

I am running my FireTV via HDMI to my DTS-capable AVR.
