But why not though? These already existed a few years ago....

And looks great on base consoles too
Those aren't generated on the fly by the console. They're handcrafted with one eye on performance, stored on your drive and just have to be loaded in, not built from procedural first principles every time you approach (i.e. likely to be moderately less taxing on the hardware).
And they don't have to hold up to being seen continuously (with no obsctruction) all the way from orbit down to the ground. You'd either have
wild amounts of pop-in as the meshes for the trees and giant overhanging mountains popped in from afar, or it would be incredibly taxing on the GPU.
I don't recognise the first screenshot, but the second two certainly are from games that (although "open world") take place on handcrafted, painstakingly planned and curated maps, that have been honed and refined time-after-time over years to squeeze out the maximum detail and wow-factor of an area that's equivalent of a small fraction of one small moon in Elite Dangerous.
Not saying landscapes like that can never be done. I think we'd all like to see Elite approach that eventually. But a) producing such landscapes in a non-cartoonish way procedurally across a whole galaxy is probably an orders-of-magnitude more complex problem than hand crafting a map, and b) if it can eventually achieve that level of complexity, we'll still have to
find it, there will probably still be comparatively boring areas.
And I would argue there
should be, because it makes finding the cool scenery an entertaining goal in itself.
I do think the boring areas should be slightly
less boring than they are now. But the game also shouldn't be giving us the Grand Canyon, or Glencoe, or the Giant's Causeway every time we land. To make that a cool moment, we sometimes need to land in the equivalent of a flat, boring field somewhere.
