If 2830 is uncracked in SF, then NF hasn't gone to it.
If that's the case, then the 480/540 issue was something unrelated to DRM.

There is no 4.10.2830.0 in StreamFab\cdm\widevinecdm or StreamFab\CEF\WidevineCdm
But if you use 4.10.2710.0 in any Chrome Browser NF offer only 540p - see post #6
SF use a trick to dl >540p without using cdm 2830 ..
.. that's why Wilson wrote "the old released videos"
and Territory from yesterday cannot be dl >540p
