Uneven sheen with low-sheen latex enamel on drywall

Our painter sprayed a primer for latex paint onto our new smoothly-textured drywall.
After a few days, he sprayed on two (2) coats of a low-sheen latex enamel.
After drying, the ceilings and walls have a number of areas that are lower/higher sheen than the rest, as seen by looking along the walls, ceilings.
Is this the inevitable downside of sheen enamel on drywall or could it be the painter/paint, etc. The painter claims a 3rd coat will fix everything.
Possibly the sheen contrast will reduce to zero over time, but I'm not optimistic.
Not sure what the primer was, but the enamel is Frazee Mirro-Glide.
Any suggestions? Thanks.

Do those areas correspond to where seams in the drywall were taped and mudded? If so - if the sheen on the drywall is different from the sheen on the mud - the cause is probably cheap primer, or not enough primer, or both. Since it was sprayed, it was probably thinned first to facilitate spraying, and probably should have had two prime coats instead of one.

Probably will.

Doubtful.
Find out what primer he used....

It is because of uneven absorption (needed more/better primer), uneven application of either/both primer and top coat or not stirring the top coat paint sufficiently to evenly distribute the flatting agent. ________________

It's the painter's problem, not yours.
