AMD PowerXpress/Enduro switchable graphics DXGI issue

Yesterday I wrote about the NVIDIA Optimus problem with DXGI where Output Protection Manager API reported Intel certificate for NVIDIA DXGI adapter.

AMD hybrid graphics known as “PowerXpress” (and most recently as “Enduro”) exhibits the same behavior:

Adapters
 AMD Radeon HD 8850M
 Intel(R) HD Graphics Family 

Adapter: AMD Radeon HD 8850M
 Vendor Identifier: 0x1002
 [...]
 Output: \.\DISPLAY1

Output Duplication

Interestingly, it seems that NVIDIA managed to resolve this problem in their most recent hybrid graphics solutions somehow (no suitable device handy), however AMD in turn seems to have this line of product discontinued at all (community forum questions look like desperate self-help service). Or I just failed to find accurate information on the topic.
