Yeah, this was my suspicion and I have no idea how hard it is. I think we lost a lot of trust when they did the initial bit and now are nervous about any perceived imperfection.
As was said up the page, it isn’t the end of the world and it helps coming here to vent/set proper expectations.

We're all on a learning curve. Quite often my older and more experienced clients naturally stick to simpler designs because they've been through problems getting more complicated designs to work.
If I was specifying a bathroom tiling job I'd 3d model it and give exact instructions/drawings to the tiler. Sometimes you start a tiling job and you just eyeball the start point from a couple of possibilities only to find out later the client sees it completely differently.

I wouldn't want to be your tiler. It's very difficult to reach the level you're expecting. Tiling in general is one of the areas that cause trades problems. I've done a lot of tiling and most of it meets the householders expectations but it's the one area where you can easily lose a client through disappointment and in most cases with the best will in the world no one is going to meet their expectations. It's also very difficult to alter unlike a lot of work.
In some cases planning makes a difference, i.e. you tell the tiler start at the window, half tiles in the corner if that's what you want. Specify exactly the edging and trim in advance etc. Choosing tile types and sizes that are sympathetic to the building/room size helps too. I've seen a few trends come and go and the metro tile is full swing right now, by the time every tradesman has done a few rooms of it the rest of the population will be giving it a rest and so the cycle starts again.
tldr, he's probably doing his absolute best and sweating bullets. If it's not grouted yet then I'm afraid you'll have to wait to see the end effect as grouting makes a big perceptual difference, especially to gap imperfections.
