Chigz answered my email for my own question for Crazed if anyone was wondering too...
" Hi, Yes that is correct. Netflix HD and 4K requires googlewidevine L1 licensing which is not easy to obtain. So only boxes with Official ATV and Official 4K Netflix are:
- Shield TV
- Mi Box
- Fire TV / Sticks
Best regards,
