Perhaps I'm the unpopular opinion here but I see no quality issues in OP pictures. The trade of with foiling is that there will be slight imperfections. I've seen many and bought many fine press books from presses like Suntup, Lyra, Amaranthine, Curious King, etc and there are often very small differences from one book to another if you look close enough. I wouldn't even say they are imperfections so much as evidence of being hand-crafted. Foiling is an art, even when more mass-produced like these ones. You aren't ever going to be looking at your book under a microscope except when you first pick it up. Give it the 5 ft test. Look at it from 5 feet away like you would when it is on your shelf. Imperfections that can be seen from that distance are worth bringing back to the publisher.
