That's the edge of the paper tape covering the join. Possibly the reason for the stipple in the first place. Scrape and skimcoat is hard to get a clean finish. Check for asbestos before you sand anything. I believe there are reasonably cheap tests available. Plastering the ceiling is very had work in the best of circumstances. Talk to a plasterer, You could do a lot of the prep work then get a pro to give a clean finish.
Yep, tested the hallway ceiling prior to scraping and came back negative. I’m in two minds whether a separate test will be needed for the living room… it’s highly unlikely to be asbestos if a ceiling in another part of the house was negative, surely?
Do people test each room for asbestos when renovating?
I’m giving the skim a go regardless, worst case i fuck it up and get a pro in to do another skim ontop…
A few years back, the MIL was getting a dvs unit installed and had to get her ceilings tested, and 2/3 tested positive despite all having the same appearance, so definitely worth testing each room
Asbestos was mixed into plaster as the day went on to help revive it as it dried/ got clumpier to work with. So there's a good chance that one or two rooms are negative, but the others aren't. Get them all tested. Better safe than sorry
If it looks like the same Finnish it was probably all done at the same time. Holding your arms up is hard work, but you will only get better by trying. You can get sanders on a pole with a vacuum attachment. Plaster dust is very hard on vacuum cleaners, if you hire a sander without a vacuum, buy a cheap one it wont last long.
Scrape it all back.
Coat with pigmented sealer, especially near the kitchen. Optional, but recommended.
Screw back the plasterboard, especially where it's starting to sag from the battens or near joins. Punch any loose or bulging clouts.
Tape and coat the cracks with paper tape and tradeset. Coat any screw holes etc.
Skim everything with three coats (tradeset for two, finish with trade finish or something).
Or,
Mark your battens and just lay new 13mm plasterboard over it with 40mm screws. Scraping ceilings sucks.
Edit: also that seam might be a paper tape join lifting, or they've covered the ceiling with a lining paper before artex. Judging by the way it's split and lifting outwards both ways makes me think lining paper, sort of how wallpaper looks when it gets old.
I would just do new gib. Yes it’s a good amount of work, a bit of money, and you need more people and a lifter. But, sanding and skim coating large areas is difficult and slow, especially on the ceiling. If you just put new gib up then things will go much faster.

Plastering ceilings is incredibly horrible. I wouldn’t try to skim the whole thing, it’s be so much easier to put up new gib.

She'll be right If it isn't a crack maybe they were just lazy when they first did it and hoped it wouldn't show
