Bingo. You have to fight tooth and nail for every entitled benefit at hotels in Vegas. With certain hotel chains they already manage to carve themselves out by name in the T&Cs to certain benefits.

There is zero chance of getting late/early checkout without paying at a Vegas hotel regardless of your loyalty status or rates (but they will happily find availability for a $50-100 surcharge) or an upgrade (but will happily offer you a suite upgrade for only $150/night at checkin while saying they have no upgrade availability), so the only real benefit for the Edit would be the property credit and breakfast.

All that said, Chase does say that The Edit benefits "vary by property and are subject to availability at check-in, but typically include [...] Daily Breakfast for Two" and when I did a dummy booking I did see that some properties don't include a daily breakfast so you know before you book.

Still, it does seem pretty pathetic by Chase and again shows why it is worse than FHR (although perhaps there are exception properties for FHR as well - I honestly don't know).

But more broadly this is just a problem with Las Vegas. I have no idea why anyone goes there anymore - everything is overpriced, service is poor, and everything seems adversarial to guests (e.g., no coffee makers in the room to try to force you to the casino floor to buy a crappy $8 black coffee, minibars that charge "on first lift" rather than after a set period of time of the item being out, etc), and there are plenty of alternative gambling destinations that offer more compelling value. Perhaps there is the unique "flare" of Vegas and certain shows, etc - but it is tough to have that compensate for everything else being absolutely terrible.
