Although you are being pedantic for the sake of arguing, you are correct in that all those shading techniques are cheating to approximate the real thing as much as possible while being cheap in real-time rendering space. Animation film or films that use CGI do that off the render farms that do it offline, one frame renders in maybe hours, and whole film is rendered in months. Why? It is using full path tracing, which is the real deal (no cheating necessary), the elusive Holy Grail of rendering for real-time. On gaming side, to render in real-time we have to contend with cheats all around to approximate the final result to a full path traced render as much as possible. All thing you said as 'well if that is cheating these are cheating' are really cheating mate. I didn't curse you or something you don't have to argue with me on the matter just because I said a bad thing about your plastic box of choice, don't choose this hill to die on.
Also, PBR was as close as you can get to real textures with reflection/refraction properties of the real thing within the context of deferred rendering in game engine in real-time. It is great and everything but if game devs could do low noise full path tracing on the console hardware in real-time graphics, they would abandon PBR and all other cheating methods in a heartbeat. But we are still a long way off that, we have to contend with cheats, and we need to get better and better at approximating the real thing while being within budget of real-time rendering....
Somehow I knew this was coming, you like to argue for the sake of arguments, but World Cup and Olympics are broadcast on TV cables and networks made up of satellites in orbit across the globe not on the back of internet network, and both have different encoding & decoding. If Sony had had bought airwave time off the TV networks to televise the event, it could very well be broadcast 4K and maybe even @60fps if it was SDR. But to do that Sony had to negotiate and buy those airtimes in each country one by one, or at least countries that matters in marketing, however as you can see it is a LOT of money and time spent on making sure top quality of content carries to the end user. The usage of internet network is free, YouTube and Twitch are free to live stream platforms, so they are free but they don't guarantee high bitrate even in lower resolutions, also Encoding your event in highest of bitrates won't matter since as soon as you upload, it will be decoded and then encoded in the platform's own shitty proprietary algorithms anyway and you don't have any say in the matter, it is a blackbox and only platform holders know the workings of that system, you can sometimes approx. bitrate on their panels (for YouTube it is under 'stats for nerds'). TL;DR -> TV broadcast and internet live streams are different.
