You sure its not wallpaper paste residue? Or is it uneven platering ?
i had the walls skimmed about 3months ago,done the usual watered down first coat and so on,it looks like the plaster is a bit grainy in places but ive given it about 5 coats with same results,its as if paint is drying so quick before i get the next roller full on,iam using dulux matt and a harris microfibre roller,iam wondering if its worth watering paint down a bit ti see if that makes any diffrence,starting to think feck it and wallpaper instead. 
You should never need to water it down(except the first coat)..Cant understand how its drying between each roller fill unless youre nipping out for a tea between dips
I wish all emulsions dried that quick as Id earn a lot more money

Did you or your plasterer sand the finished plaster?
After a mist coat. I always thin the subsequent coats a little to help flow out.
I can't say I ever applied dulux trade matt unthinned.
Cut in first, then roll keeping the edge 'green', don't roll till roller is dry keep it loaded. i.e apply like your not paying for the paint. No texting or tea till u finish each wall
Good luck

Always mist coat green plaster with matt emulsion thinned 25-30% & apply 2/3 coats in quick sucession to keep it wet; or use a plaster primer. If you don't, the paint won't stick properly but you may not realise that until the 1st time you decorate a few years later but it could crack & fall of the wall much earlier as it dries out!
only bits that got a light sand were a couple of (iffy) bits that i used lightweight filler on,its only when you look at it in a certain direction its noticeable,just a thought but could i lay paint on really thick on thes areas ?or do i just give up.........
The paint will usually look slightly lighter on smooth areas compared to the 'rougher' patches in the same way two pieces of white paper , one smooth the other 'toothed' , will seem a different tones
Finishing plaster is not meant to be sanded to any degree as this will expose the grain making some patches more absorbent than others. This leads to a patchy finish that looks a bit like a suede coat brushed the wrong way; it should cover eventually, it will just need more coats of thicker paint.
Except for the odd light trowel mark on a bad day, a newly plastered wall shouldn’t need any filler if it’s been done properly by a competent spread & the finish should never need sanding unless it’s been wrongly over polished; in this case a light buffing is all thats needed.

TRADE emulsion ( Dulux, Crown etc.,) from a TRADE shop, its thicker/undiluted unlike DIY (Homebase/B&Q etc) stuff
