Decided to post some info I found.
----
S/PDIF (tech-faq.com) - "Although the SPDIF protocol doesn’t specific a max resolution or data rate, the equipment which uses the SPDIF connectors has to determine the data rate..."
S/PDIF - Wikipedia - "...has no defined data rate. Instead, the data is sent using biphase mark code, which has either one or two transitions for every bit..."
Digital Data Digital Signal - NRZ (Non-Return-to-Zero), BMC (Biphase Mark Code).
S/PDIF - HwB (hardwarebook.info) - IEC 60958-3 specifies up to 768 kHz sampling frequency.
IEC-60958-3 | Digital audio interface - Part 3: Consumer applications - IEC 60958-3:2021.
--
Representing Formats for IEC 61937 Transmissions - Win32 apps | Microsoft Docs
Looks like I muddled aggregates with frame rates?

====
Even current HDMI-DP devices could be utilizing Toslink JIS F05 (the current one) or SMI for 'audio only':
* Correction SMI, not SMA.
119mbps, requiring just under 5k aggregate.
