Most notably, you will not get any deinterlacing. Its also shown to not be fully stable with madVR quite yet (future madVR versions will hopefully improve on that), and its Copy-Back mode is more resource intensive then DXVA2-CB.
The issue with the sample in this thread is also already fixed in the latest development version of LAV Filters, so the next release will rectify it with default settings.

Thanks, Hendrik.

I switched to D3D11 mode specifically because it seemed to be more stable with Media Center.

Copy-Back has no impact on the renderer, it just behaves like software decoding, but as said above, D3D11 copy-back is also measurably more resource intensive for not yet fully clear reasons.

Thanks Hendrik
@fitbit. I'd either temp remux for now or manually update LAV

The remuxing has audio sync issues.
For now I am content to have HA turned off or use ROStd for that one series. When MC incorporates the latest builds of LAV, I'll simply switch back to ROHQ. ROHQ is the only way I can watch HDR content properly on my SDR TV.
