TL;DR you cannot go on air in 8bit in UHD.

I had a second look at HLG3 footage, and indeed it looks as flat as S-log, so most SDR viewers probably won't be able to stomach it if you were to feed it to a broadcast H.264 stream. So even if you could software-upgrade HDR TVs to recognise HLG3 somehow, it's still out of the question due to how bad it looks on SDR displays.

I guess most H.264 HD channels will do tone-mapped content (from HDR) and call it a day. Which means the handling of tone-mapped content will be a big differentiator for consumer HDR TVs for the years to come, much like the quality of upscaling and denoising of mpeg2 SD channels was a big differentiator for early consumer HD TVs (and still is in some countries like the UK, which has 12 HD channels and several dozen Mpeg2 SD ones, all of them at crappy bitrates).

The problem ain't UHD, the problem is the fact that Hotbird is overcrowded and bitrate is expensive as f...

Terrestrial is the big problem IMO. Many of us in the EU and UK live in rented apartments and cannot drill holes through walls and mount satellite dishes outside.

A terrestrial DVB-T2 mux can fit a grand total of 3 UHD channels. Indeed, any countries doing UHD trials are broadcasting just 2-3 UHD channels on one mux, and I doubt they will manage to free up more than one mux due to the 4G and 5G spectrum releases (and terminating H.264 is out of the question considering some countries are still facing resistance when trying to terminate mpeg2). So, I disagree, UHD bitrate requirements are very much a problem. The terrestrial broadcasting world should have waited for VVC so they can at least get 6 UHD channels per mux. If you though HD was a failure on terrestrial, wait and see how UHD will do.
