4K discs are so niche that this just isn’t really true, since they simply don’t bother to add that stuff anymore with the money all going to streaming. Almost every 4K disc I have just loads right into a bland generic menu with only a skippable logo for universal or whatever at the beginning. On top of that, they’re all region free. Odd that when the consumer base for physical media is smaller than it used to be, the consumer experience is better.

Now most of these 4K discs also come with a regular (often older) Blu-ray which contains the features from previous releases or whatever, and THAT’S where the bullshit you’re talking about is - lots of trailers (with it being a crapshoot whether you can skip straight to the menu, need to skip one at a time, or have to actually fast forward them), and, worst of all, defunct BD-Live stuff that in some cases you have no way to skip loading at all, even if you completely disable network connectivity in the player. None of this junk is in any of my 4Ks. Sometimes the features are even on the 4K too, if you’re really lucky.

But yeah, modern 4K discs are mostly great and still absolutely way better video and audio quality than any streaming service I’ve used - the worst thing you usually get is maybe one dumb copyright notice. (LG’s 4K players were terrible anyway though making the experience bad for consumers for a different reason, but that’s for another comment).
