Not much difference in b:

HDMI 2.0b was released March, 2016.[119] HDMI 2.0b initially supported the same HDR10 standard as HDMI 2.0a as specified in the CTA-861.3 specification.[117] In December 2016 additional support for HDR Video transport was added to HDMI 2.0b in the recently released CTA-861-G specification, which extends the static metadata signaling to include Hybrid Log-Gamma (HLG).

In short either at crappy 30Hz, or 60Hz with crappy chroma subsampling compression.
