Off the top of my head, if the rings were a narrow band around the Earth, and were aligned with the terrestrial equator, they would be less visible from high or low latitudes. If they were aligned with the plane of the ecliptic, then they would be visible as a band following the 'zodiac constellations', and thus visible much further North and South.
At night, in the shadow of the Earth, I'd think that they would be dark, perhaps even invisible. Perhaps moonlight would serve to illuminate them, depending on the relative position of the Sun and Moon.
I'd guess they would look most impressive around and dusk. The particle density and albedo would influence whether they would be visible during full daylight. The ring density would affect whether they had sharp edges or simply faded out away from the centre.
Ron Miller is an artist who made some very nice visualizations. I can’t vouch for the scientific accuracy, but they seem plausible enough to me, and consistent with the images I’ve seen of Saturn’s rings from nearby probes.

The only explanation I've heard for Musk's political antics that makes cold sense.
Yeah this. I was 50 miles from civilisation in some mountains in central Asia last year trying to do astrophotography and I had to edit out the flying space trash after!
If you needed rescuing from there, or if a nearby village was affected by a natural disaster, this flying space trash is what's saving lives.
It makes sense for the vast majority of people to prefer that against the slight inconvenience in editing out satellite tracks faced by a tiny tiny community of ground bases astrophotographers.
Low orbit satellites are unnecessary for emergency/comm. Fewer, dimmer, satellites at higher orbits are actually cheaper, but LEO constellations are now subsidized by the military industrial complex (there is other value to be low).
There isnt nearly enough mass up there in all the foreseeable sat constellations. They need enough collective mass to overcome the extreem orbital inclinations/speeds we use for sats. For a visible ring to form, we would have to send billions of sats into high/slow orbits and then just forget about them for millions of years. Even then, they would likely form into mini moons first before those moons eventually broke up into rings.
I had to laugh thinking that we (or some alien race) might come across a ringed planet only to find its rings are made of orbital space junk from a long-dead species that once flourished on the planet.
This made me consider what sort of orbital archeology would take place. I imagine it would be a gold mine for anyone trying to study that civilization, and attempting to snatch pieces out of orbit would be a huge focus.

Nice opening image, but what would the view be like from Earth?

May see rings around Earth again.. it's the expected state that space debris settles into after Kessler Syndrome.
I was about to make a snarky comment about starlink. It's getting harder to take a shot of the sky without one of those pesky floaties.
Debris left in orbits below 600 km normally fall back to Earth within several years. The Starlink constellation is at around 350 km and below.
Starlink is actually 550 km and Amazon's Kuiper at 620 km.
But the missile interceptors for the orbital 'American Iron Dome'* in the news lately would be ~ 350 km.

You are right, it looks like I got a mistaken number from the Reddit (who could have predicted that).
It says here that earlier this year Starlink was seeking permission to go lower. I wonder how that went.

hopefully the sight encourages them from leaving their own waste behind
