If the romex jacket labels are correct that install is 95% legit from what I can actually see. That is if the thhn in the emt is derated correctly.
Are the pvc 90's only sleeves for romex? If so and they're less than 24" they may be ok without derating too.
The only real wtf I see is the bare gnd wire looped around the cover screw at lower left of box, prolly easy fix.
Looks like something got remodeled and sparky cut existing emt, put in jbox and extended ckts with romex in pvc sleeves, or ran new emt to meet existing romex ckts. Not atypical in a remodel.
Splices look good with non-HD wire nuts. You're lucky they didn't stuff everything into a 6"x6"x6" jbox and leave 2" of wire for each splice.
It'll look nice and neat with the cover on.
Just my professional opinion
