The former.
iPhones and Intel CPUs have hardware that decodes many different codecs, including vp9 and h264. iOS and OSX have drivers that make hardware decoding available for h264, however they do not make available vp9 decoding, despite the fact that the hardware is perfectly capable of doing it.
So you fallback to software decoding, which is problematic at 4k/60fps. People falsely blame YouTube/Google, when it's actually Apple's problem.
