I tried a lot of png images and all of them fade in color

Window on the left, original image on the right

HR(Tool::_IdcDevice->CreateTargetForHwnd(mainWindow, TRUE, &IdcTarget));
HR(Tool::_IdcDevice->CreateVisual(&IdcVisual));

RECT windowRect;
GetClientRect(mainWindow, &windowRect);
HR(Tool::_IdcDevice->CreateSurface(
    windowRect.right - windowRect.left, windowRect.bottom - windowRect.top,
    DXGI_FORMAT_R16G16B16A16_FLOAT, DXGI_ALPHA_MODE_PREMULTIPLIED,
    &IdcSurface
));
HR(IdcVisual->SetContent(IdcSurface));

HR(IdcTarget->SetRoot(IdcVisual));
HR(Tool::_IdcDevice->Commit());

POINT offset;
CComPtr<IDXGISurface> _Surface_DXGI_Draw;
HR(IdcSurface->BeginDraw(
    NULL, __uuidof(IDXGISurface), reinterpret_cast<void**>(&_Surface_DXGI_Draw), &offset
));

D2D1_BITMAP_PROPERTIES1 properties = { };
properties.pixelFormat = D2D1::PixelFormat(DXGI_FORMAT_R16G16B16A16_FLOAT, D2D1_ALPHA_MODE_PREMULTIPLIED);
properties.dpiX = properties.dpiY = 96;
properties.bitmapOptions = D2D1_BITMAP_OPTIONS_TARGET | D2D1_BITMAP_OPTIONS_CANNOT_DRAW;
properties.colorContext = NULL;
HR(Tool::_D2dDeviceContext5->CreateBitmapFromDxgiSurface(
    _Surface_DXGI_Draw, properties, &ExchangeChainsBitmap
));

Tool::_D2dDeviceContext5->SetTarget(ExchangeChainsBitmap);
Tool::_D2dDeviceContext5->BeginDraw();
Tool::_D2dDeviceContext5->Clear(NULL);

CComPtr<ID2D1Bitmap> img;
HR(Tool::LoadPngAsBitmap(_T("xxx"), &img));
Tool::_D2dDeviceContext5->DrawBitmap(img);

HR(Tool::_D2dDeviceContext5->EndDraw());
HR(IdcSurface->EndDraw());
HR(Tool::_IdcDevice->Commit());

//====================================================================================

HRESULT Tool::LoadPngAsBitmap(_In_ PCWSTR uri, _Outptr_ ID2D1Bitmap** bitmap)
{
    HRESULT hr = S_OK;

    CComPtr<IWICStream> stream;
    HR(Tool::_IWICFactory2->CreateStream(&stream));

    HR(stream->InitializeFromFilename(uri, GENERIC_READ));


    CComPtr<IWICBitmapDecoder> decoder;
    HR(Tool::_IWICFactory2->CreateDecoderFromStream(stream, NULL, WICDecodeMetadataCacheOnLoad, &decoder));


    CComPtr<IWICBitmapFrameDecode> frameDecode;
    HR(decoder->GetFrame(0, &frameDecode));


    CComPtr<IWICFormatConverter> converter;
    HR(Tool::_IWICFactory2->CreateFormatConverter(&converter));


    HR(converter->Initialize(frameDecode, GUID_WICPixelFormat32bppPBGRA, WICBitmapDitherTypeNone, NULL, 0.0f, WICBitmapPaletteTypeCustom));
    HR(Tool::_D2dDeviceContext5->CreateBitmapFromWicBitmap(converter, NULL, bitmap));
    return hr;
}

I tried to save the bitmap created by LoadPngAsBitmap back to a file and he has the correct colors. I guess the problem is related to alpha premultiplication, but I don’t know how to fix it
